Our Vision

We believe
that the Internet should be accessible to everyone, not just to access information but also to develop, create and contribute.

We see many similarities in our vision with the desktop revolution, when computer hardware and software evolved to provide everyone with
the capability to develop, create and print professional-quality documents from their desktop. Access expanded to everyone, document creation became a core human skill, and the asset-heavy approach was abandoned. This same revolution has not yet
happened online. Today, professional skill and capital is needed to turn ideas into high-quality web content. We believe that by providing an easy-to-use and affordable solution with professional-quality results, we are leading the Webtop
Revolution.

Our Business

We are a leading global web development platform with one of the largest number of registered users in the world. We empower more than 37 million registered users in 190 countries to create and
manage a fully integrated and dynamic digital presence. We are pioneering a new approach to web development and management that provides an easy-to-use yet powerful cloud-based platform that eliminates the need for complex coding and supplants
expensive design services. Our solutions enable millions of businesses, organizations, professionals and individuals to take their businesses, brands and workflow online. We offer our solutions through a freemium and subscription model and as
of August 31, 2013, we had 679,536 premium subscriptions.

Our core product is a drag-and-drop visual development and editing
environment complete with high quality templates, graphics, image galleries and fonts. With our platform, Wix users can create and manage a professional-quality digital presence tailored to their brands specific look and feel, accessible
across all major browsers and the most widely used desktop, tablet and mobile devices. Our cloud-based platform is accessed through a hosted environment, allowing our users to update their site and manage their business or organization at any time.
We provide our users with flexibility and scalability, allowing them to expand their digital presence as their business, organizational, professional or individual needs change and grow. Through our highly curated App Market, which we launched in
the last quarter of 2012, we offer users the ability to easily install more than 140 different apps that were carefully identified and selected for inclusion in the App Market by us based on user needs and demand. These apps add additional
functionality and are easily integrated into users websites with one click and without any coding. Revenues from our App Market have been negligible to date.

Our scale and reach makes us an attractive partner for companies interested in distributing their own solutions to our users, which are primarily small business owners, organizations and entrepreneurs. As
we expand our platform through partnerships, we are able to increase our value proposition for existing users and more easily attract new users.

By developing business intelligence using the data we have generated over several years of operation, we have been able to leverage online channels effectively for the majority of our marketing efforts
without the need for a direct sales force. In addition, many of our users refer us within their personal and professional networks.

As a result, we generate a large volume of traffic through word-of-mouth, with organic and direct traffic, meaning visitor traffic that reached our website, Wix.com, via unpaid search results or
by typing the URL of our website in their browser, accounting for approximately 59% of the premium subscriptions generated by users that registered in August 2013.

We are removing not only technological, but also geographic and linguistic barriers to web development by offering our platform in several languages, including English, French, Spanish, Portuguese and
Italian.

Through June 30, 2013, we had achieved 14 consecutive quarters of sequential growth in the number of premium
subscriptions. We have also achieved 14 consecutive quarters of growth in revenues and collections. We had revenues of $9.9 million, $24.6 million and $43.7 million and collections of $13.8 million, $29.6 million and
$52.5 million in 2010, 2011, and 2012, respectively. We had a net loss of $11.5 million, $22.7 million and $15.0 million in 2010, 2011, and 2012, respectively. We had revenues of $34.1 million, collections of $41.9 million and a net
loss of $10.1 million during the six months ended June 30, 2013.

Industry Background

Increasing need for a dynamic digital presence

According to a June 2013 Netcraft survey, there are more than 673 million websites across all domains, nearly four times the number that existed five years ago. The way that consumers interact with
websites, however, continues to expand with the evolution of technology. Consumers have come to expect a high level of personalization, engagement and functionality; a static website is no longer satisfactory and can even negatively affect overall
brand perception for businesses, organizations and professionals.

In the current market, businesses, organizations and
professionals need a dynamic digital presence with tools to manage interactions with customers, suppliers, partners and employees online and in real time. These interactions include back-end activities like invoicing, customer relationship
management and payment processing, as well as front-end activities such as communications, online marketing, reservations and scheduling and social media integration.

Use of dynamic web content and services for high level customer engagement is becoming increasingly prolific. Businesses, organizations and professionals that have access to the latest technology and
large budgets are able to create this fully functional, integrated and engaging digital presence and widen the competitive gap between themselves and those that lack access.

Creating a dynamic digital presence is challenging

Building this
presence is becoming more challenging for businesses, organizations, professionals and individuals for the following reasons:



Developing a dynamic digital presence with professional quality is expensive. Developing and maintaining a professional-quality digital presence
today often requires the engagement of professional designers and developers, which is not an option for many small businesses with limited budgets.



Learning to code is difficult, time consuming and out of reach for most. As coding languages continue to evolve over time to allow for
additional features and functionality, the complexity and level of skill required to develop a digital presence increases dramatically. As a result, these professional-quality improvements are generally out of reach for those that have limited or no
experience with computer programming.



The ability to manage and modify in real time is limited and time consuming. Hiring a third-party to dynamically update a site is costly,
impractical and often time consuming even for relatively small changes. Most website template solutions provide options but have limited flexibility in terms of what can be changed once a website is published.

There are many platforms, browsers and devices which each have different compatibility requirements. In order to develop a digital presence that
is widely accessible across the growing number of platforms, browsers and devices, there is often a need to recreate an entire site multiple times with different specifications. This is costly and time consuming for even the largest companies.

Our Solution

We offer our web development, design and management solutions and apps through a cloud-based online platform that enables our more than 37 million businesses, organizations, professionals and individuals
to create a sophisticated and professional digital presence. Our large user base provides our partners with a massive distribution channel for their products, enhancing the value we can provide our users.

Benefits to Our Users

We believe that our solution offers the following key benefits to our users:



Professional quality at an affordable price. We provide customizable and professionally designed content, allowing users to encapsulate their
vision consistent with their brand and establish credibility. We have a dedicated team of over 40 design professionals, and users may access our professional content and features at a material discount to the cost of hiring a professional or in many
cases at no cost at all.



Easy-to-use technology. Our platform provides our users with a powerful and easy-to-use cloud-based solution that takes the technological
complexity out of web development and management, allowing anyone to create a dynamic digital presence. Our drag-and-drop editing environment enables users with basic computer skills to create a fully functional digital presence without the need to
develop an advanced new skill set.



User-driven website management. Our cloud-based platform makes ongoing management simple, enabling users to maintain their dynamic
digital presence at any time without the need to pay for expensive design professionals to make even small changes. We also have an in-house team of 130 support and call center professionals available for our users.



Access to third-party apps.We offer a selection of over 140 free and paid apps through our highly curated App Market that were
carefully identified and selected for inclusion in the App Market by us based on user needs and demand. These apps provide online workflow and management tools that users can add through the Wix Editor. The required coding is managed automatically
by our proprietary software without any effort needed by the user, making integration with our users sites seamless.



Multi-platform. Our technology addresses the challenges posed by the wide range of browsers and devices used to access the web. We handle all
the code customizations and required site compatibility with new device and browser platforms, removing additional cost and effort for our users.

We believe that our solution offers the following key benefits to our partners:



Distribution to a large user base. We attract interest from multiple companies seeking to market their solutions effectively to our large and
highly engaged audience of businesses, organizations, professionals and individuals through free and paid apps available in our App Market, as well as other offers, features and services.



Seamless integration of offered solutions.We help developers get their products discovered and provide easy installation and
integration. We also collect and process payments from our users for paid apps, further reducing friction for both our users and our partners.

Our Strengths

We believe the following key strengths provide us with
competitive advantages:



Proprietary technology platform. Our core strength is our technology that reduces the challenges and complexities of web development and
management for our users. Our environment enables simple drag-and-drop functionality, and our use of HTML5 gives our users the ability to easily incorporate video, audio, fonts, graphics and animations into their site. Our users also benefit
from enhanced workflow functionalities through the seamless integration of third-party apps.



Large user base and growing global ecosystem.As of August 31, 2013, we had over 37 million registered users across 190
countries and offer our platform in several languages, empowering our users to create and manage a digital presence in their own language. As our community grows, we become increasingly valuable as a distribution channel for partners and developers,
who in turn expand our offering to our users with additional features and services through the development of apps.



Superior design and content. More than 10% of our workforce is comprised of designers. We believe this investment in design provides our users
with a superior starting point and allows them to create a visually engaging and professional-quality digital presence.



Efficient marketing and customer acquisition.Our marketing activities are based on a constant analysis of behavior response data
generated on our platform, enabling us to operate different marketing campaigns efficiently across a variety of advertising channels and without a direct sales force.



Embedded solution for our users. As the basis of their online operating platform, Wix becomes a core aspect of our users businesses. Our
solutions are designed to cater to the varying needs of most business categories while supporting users throughout the evolution of their business lifecycle, greatly increasing the likelihood that they remain users.

Our Strategy

Key
elements of our strategy include:



Growing our user base. The value of our platform continues to increase as our user base expands. We intend to continue to build our user base in
the following ways:



Leveraging our data to increase and optimize our paid marketing. We will continue to leverage the intelligence derived from the large quantities
of marketing data we have gathered since our launch to optimize our marketing spend.



Growing our brand. We plan to invest in brand marketing initiatives that will further associate Wix as the go-to platform for web development
and management, increasing our long-term ability to acquire users.

Expanding to underserved geographic markets.We plan to make our solution, support and communication channels available in more languages
and expand our billing infrastructure to drive growth in underserved geographic markets.



Developing new solutions. We intend to create additional value for our users and increase our platforms monetization in the following
ways:



Investing in product development to offer additional services. We plan to leverage our experience and knowledge in web development and workflow
management to build new solutions, such as apps, data management and mobile solutions that our users need to operate and succeed online.



Expanding our partner ecosystem. We will seek to attract more partners that will provide our users with free and paid apps through our App
Market as well as other features and services, further enriching our solutions and creating additional monetization opportunities.

Risk Factors

Investing in our ordinary shares involves risks. You should
carefully consider the risks described in Risk Factors beginning on page 11 before making a decision to invest in our ordinary shares. If any of these risks actually occurs, our business, financial condition or results of operations
would likely be materially adversely affected. In such case, the trading price of our ordinary shares would likely decline, and you may lose all or part of your investment. The following is a summary of some of the principal risks we face:



Our results of operations and future prospects will be harmed if we are unable to attract new registered users and premium subscriptions at a
sufficient rate.



Our results of operations would be adversely affected if our selling and marketing activities fail to generate traffic to our website, users and
premium subscriptions at levels that we anticipate.



Our limited operating history in a new and developing market makes it difficult to evaluate our current business and future prospects, and may increase
the risk that we will not be successful.



We have a history of operating losses and may not be able to achieve profitability in the future.

If we are unable to maintain and enhance our brand, or if events occur that damage our reputation and brand, our ability to expand our base of users
and premium subscriptions may be impaired, and our business and financial results may be harmed.



Our results of operations and business could be harmed if we fail to manage the growth of our infrastructure effectively.



Failures of the third-party hardware, software and infrastructure on which we rely, including third-party data center hosting facilities, could
adversely affect our business.



We rely on search engines and social networking sites to attract a meaningful portion of our users, and if those search engines or social networking
sites change their listings or policies regarding advertising, or increase their pricing or suffer problems, it may limit our ability to attract new users.



We may face challenges expanding our premium subscription base and increasing revenues in emerging markets due to difficulties in these markets
associated with payment collections as well as legal, economic, tax and political risks that are greater than more developed markets.



We face potential liability and expense for legal claims based on the content on our platform.

Activities of users or the content of their websites could damage our reputation and brand, or harm our ability to expand our base of users and premium
subscriptions, and our business and financial results.

See Non-GAAP Financial Measures for how we define and calculate collections and free cash flow, a reconciliation of these non-GAAP financial measures
to the most directly comparable GAAP measures, and a discussion about the limitations of these non-GAAP financial measures.

(6)

Number of registered users at period end is defined as the total number of users, including those who purchase premium subscriptions, who are registered with Wix.com
with a unique email address at the end of the period. The length of time that users take following registration to design and publish a website varies significantly from hours to years, and many users never publish a website. We have no means of
assessing the level of engagement of a particular user following registration or how close a user is to potentially publishing their website. Accordingly, our use of the term user herein is not intended to necessarily indicate a level of
engagement. See Risk FactorsRisks Related Our Business and Our IndustryThe number of our registered users may be higher than the number of actual users and we have no means of assessing the level of engagement of a particular user
following registration.

(7)

A single user can purchase multiple premium subscriptions. Our premium subscriptions in any given period are derived from users that registered with us during that
period and a range of prior periods with the largest contribution from most recently registered users. See Managements Discussion and Analysis of Financial Condition and Results of OperationsOverviewPremium Subscription
Analysis.

Non-GAAP Financial Measures

Collections

Collections is a non-GAAP financial measure that we
define as total cash collected by us from our customers in a given period. Collections is calculated by adding the change in deferred revenues for a particular period to revenues for the same period. Collections consists primarily of amounts from
annual and monthly premium subscriptions by users, which are deferred and recognized as revenues over the terms of the subscriptions and payments by our users for

domains, which are also recognized ratably over the term of the service period. The following table reconciles revenues, the most directly comparable U.S. GAAP measure, to collections for the

For a description of how we use collections to evaluate our business, see Managements
Discussion and Analysis of Financial Condition and Results of OperationsKey Financial and Operating Metrics. We believe that this non-GAAP financial measure is useful in evaluating our business because it is a leading indicator of our
revenue growth and the growth of our overall business. Nevertheless, this information should be considered as supplemental in nature and is not meant as a substitute for revenues recognized in accordance with U.S. GAAP.

Capital expenditures consist primarily of investments in leasehold improvements for our office space and the purchase of computers and related equipment.

For a description of how we use free cash flow to evaluate our business, see Managements Discussion
and Analysis of Financial Condition and Results of OperationsKey Financial and Operating Metrics. We believe that this non-GAAP financial measure is useful in evaluating our business because free cash flow reflects the cash surplus
available or used to fund the expansion of our business after payment of capital expenditures relating to the necessary components of ongoing operations. Nevertheless, this information should be considered as supplemental in nature and is not meant
as a substitute for net cash flows from operating activities presented in accordance with U.S. GAAP.

Other companies,
including companies in our industry, may calculate collections and free cash flow differently or not at all, which reduces their usefulness as a comparative measure. You should consider collections and free cash flow along with other financial
performance measures, including revenues, net cash used in operating activities, and our financial results presented in accordance with U.S. GAAP.

This offering and an investment in our ordinary shares involve a high degree of risk. You should consider carefully the risks described
below and all other information contained in this prospectus, before you decide to buy our ordinary shares. If any of the following risks actually occurs, our business, financial condition and results of operations could be materially and adversely
affected. In that event, the trading price of our ordinary shares would likely decline and you might lose all or part of your investment.

Risks Related to Our Business and Our Industry

Our results of operations and future prospects will be harmed if we are unable to attract new registered users and premium subscriptions at a sufficient rate.

The number of new registered users we attract is a key factor in growing our premium subscription base, which in turn drives our revenues
and collections. To date, we have grown the number of registered users and premium subscriptions through the provision of complimentary user-friendly, drag-and-drop web development, design and management software, which can be upgraded to a
subscription-based package with various additional solutions and services. Over half of our new premium subscriptions in any given month are generated by users who registered in earlier months. We therefore attribute considerable importance to
continued growth of our user base since they are our primary source of premium subscriptions. Although we do not expect to maintain the same period-over-period user and premium subscription growth rate that we have experienced in recent quarters, we
do seek to add a larger absolute number of registered users and premium subscriptions each quarter in the immediate future. A number of factors could impact our ability to attract new registered users and premium subscriptions, including:



the quality and design of our platform compared to other similar solutions and services;



our ability to develop new technologies or offer new products and service offerings;



the pricing of our solutions and services compared to our competitors;

Our results of operations would be adversely affected if our selling and marketing activities fail to generate traffic to our website, users and
premium subscriptions at the levels that we anticipate.

We acquire many of our users through paid marketing channels,
such as cost-per-click advertisements on search engines and social networking sites and targeted and generic banner advertisements on other sites. A portion of the users acquired through these channels purchase premium subscriptions over time. In
order to maintain our current revenues and grow our business, we need to continuously optimize marketing campaigns aimed at acquiring new registered users and premium subscriptions. In the years ended December 31, 2010, 2011 and 2012 and the
six months ended June 30, 2013, selling and marketing expenses were $9.8 million, $21.6 million, $29.1 million and $22.6 million, respectively, representing 100%, 88%, 67% and 66% of our revenues, respectively. We conduct search engine
optimization and A/B testing, a marketing approach which aims to identify which changes to our website will increase or maximize user interest and user acquisition. We also rely upon the assumption that historical user behavior can be extrapolated
to predict future user behavior, and we structure our marketing activities in the manner that we believe is most likely to encourage the user behaviors that lead to desired future outcomes, such as purchasing premium subscriptions. However, we may
fail to accurately predict user acquisition, interest, or to fully understand or estimate the conditions and behaviors that drove historical user behavior and thus, fail to generate the return on marketing we expected. For example, events outside
our control, such as announcements by our competitors or other third-parties of significant business developments, have in the past adversely affected the returns we had anticipated on our marketing expenses in the short-term. If any of our
marketing campaigns prove less successful than anticipated in attracting users and

premium subscriptions, we may not achieve our return-on-investment targets, and our rate of user and premium subscription acquisition may fail to meet market expectations, which could have a
material adverse effect on our share price.

Our limited operating history in a new and developing market makes it difficult to evaluate
our current business and future prospects, and may increase the risk that we will not be successful.

We were founded
in 2006 and the majority of our revenue growth has occurred since 2011. This short history makes it difficult to assess effectively our future prospects. We also operate in a new and developing market that may not develop as expected. We believe
that the growth in our user base and revenues may indicate that our business strategy is successful, but you should consider our future prospects in light of the challenges and uncertainties that we face, including the fact that our business has
grown rapidly and it may not be possible to discern fully the trends that we are subject to, that we operate in a new and developing market, and that elements of our business strategy are new and subject to ongoing development.

We have a history of operating losses and may not be able to achieve profitability in the future.

We have incurred net losses in each fiscal year since our inception and, as of June 30, 2013, we had an accumulated deficit of $69.9
million. We expect that our operating expenses will continue to increase in the near term at a rate that will offset all or substantially all of any future growth in revenues. We believe that this increase in operating expenses will result primarily
from increased selling and marketing expenses related to user acquisition activities and increased research and development expenses related to enhancing the functionality of our solutions. We seek to leverage these expenses across a growing base of
premium subscriptions while maintaining or increasing the amount of revenues per premium subscription in order to achieve profitability. As a result, if we are unable to grow our premium subscriptions at the required rate or to maintain or increase
revenues per user, or if we incur unexpected expenses, we may be unable to achieve or sustain profitable operations.

The rate at which annual premium subscriptions are purchased and the rate at which premium subscriptions are renewed significantly impact
the overall number of premium subscriptions and, as a result, our collections and our revenues. Our annual subscription renewal rates have historically increased based on the length of time a subscription has been active. One of the key drivers of
renewal rates is whether premium subscriptions are annual or monthly. Annual subscriptions have higher renewal rates than monthly subscriptions since there is one-twelfth as many opportunities in a given annual period to fail to renew a subscription
than a monthly subscription whether deliberately or through failure to update credit card information upon expiration. As such, our overall renewal rates may drop if there is a decrease in the number of premium annual subscriptions compared to
premium monthly subscriptions, and will affect our ability to forecast our future results of operations. If the number of annual premium subscriptions or renewal rates fail to meet our expectations, our profitability and future prospects may be
adversely impacted.

If we are unable to maintain and enhance our brand, or if events occur that damage our reputation and brand, our
ability to expand our base of users and premium subscriptions may be impaired, and our business and financial results may be harmed.

Maintaining, promoting and enhancing the Wix brand is critical to expanding our base of users and premium subscriptions. For both users and premium subscriptions, we market our solutions and services
primarily through cost-per-click advertisements on search engines and social networking sites, participation in social networking sites, and free and paid banner advertisements on other websites, and small Wix advertisements on our users
websites that do not currently have a premium subscription. Our ability to attract additional users depends in part on increasing our brand recognition. In addition, our solutions and services are also marketed through free traffic sources,
including customer referrals, word-of-mouth and direct searches for our Wix name, or web presence solutions, in search engines. Maintaining and enhancing our brand will depend largely on our ability to continue

to provide high-quality, well-designed, useful, reliable, and innovative solutions and services, which we may not do successfully. We may introduce new solutions or terms of service that users do
not like, which may negatively affect our brand. Additionally, if users have a negative experience using third-party applications and websites integrated with Wix, such an experience may affect our brand. Our Wix Arena Marketplace enables
independent web designers to offer their services to users who engage them directly. As we conduct only a limited evaluation of these designers credentials, our reputation may be harmed if any of the services provided by these independent
designers do not meet users quality expectations. Maintaining and enhancing our brand may require us to make substantial investments and these investments may not be successful. Additionally, errors, defects, disruptions or other performance
problems with our products and platform, including the products and solutions we license from third parties, may reduce our revenue, harm our reputation and brand and adversely affect our ability to attract new users and premium subscriptions,
especially if these errors occur when we introduce new services or features. If we fail to successfully promote and maintain the Wix brand or if we incur excessive expenses in this effort, we could be subject to claims regarding our business and
financial results may be adversely affected.

Our results of operations and business could be harmed if we fail to manage the growth of
our infrastructure effectively.

We have experienced rapid growth in our business and operations, which places
substantial demands on our operational infrastructure. The scalability and flexibility of our cloud-based infrastructure depends on the functionality of our third-party servers and their ability to handle increased traffic and demand for bandwidth.
The significant growth in the number of users and transactions has increased the amount of both our stored marketing and research data and the data of our users. Any loss of such data due to disruptions in our infrastructure could result in harm to
our brand or reputation. Moreover, as our user base grows, and as users use our platform for more complicated tasks, we will need to devote additional resources to improving our infrastructure and continuing to enhance its scalability in order to
maintain the performance of our platform and solutions. Our need to effectively manage our operations and growth will also require that we continue to assess and improve our operational, financial and management controls, reporting systems and
procedures. We may encounter difficulties obtaining the necessary personnel or expertise to improve those controls, systems and procedures on a timely basis relative to our growth. If we do not manage the growth of our business and operations
effectively, the quality of our platform and efficiency of our operations could suffer, which could harm our results of operations and business.

Failures or loss of the third-party hardware, software and infrastructure on which we rely, including third-party data center hosting facilities, could adversely affect our business.

We rely on leased servers and other third-party hardware and infrastructure to support our operations. Our primary
data centers are in two geographically separate locations in the United States with a back-up data center in Europe. We lease our primary data centers in the United States from Hostway Services, Inc. pursuant to purchase orders issued under an
agreement that automatically renews on an annual basis unless terminated by us by notice at least 60 days before the annual renewal date or by either party at any time with 180 days advance notice. If Hostway ceases to make these data centers
available to us without sufficient advance notice, we would likely experience delays in delivering our solutions until migration to an alternate data center provider is completed.

Furthermore, the owners and operators of these facilities do not guarantee that our users access to our platform will be
uninterrupted or error-free. We do not control the operation of these facilities, and such facilities could be subject to break-ins, computer viruses, sabotage, intentional acts of vandalism and other misconduct. For example, in the past, one of our
hosting providers was subject to cyber-attacks and another experienced damage from a fire, both of which caused interruptions in our service. Further, our servers and data centers are vulnerable to damage or interruption from natural disasters,
terrorist attacks, power loss, telecommunications failures or similar catastrophic events. Moreover, if for any reason our arrangement with one or more of the providers of the servers that we use is terminated, we could incur additional expenses in
arranging for new facilities and support. Disruptions to these servers could interrupt our ability to provide our platform and solutions and materially and adversely affect our business and results of operations.

We rely on search engines and social networking sites to attract a meaningful portion of our users,
and if those search engines or social networking sites change their listings or policies regarding advertising, or increase their pricing or suffer problems, it may limit our ability to attract new users.

We rely on search engines and social networking sites to attract new users, and many of our users locate our website and solutions by
clicking through on search results displayed by search engines such as Google and Yahoo!, and advertisements on social networking sites such as Facebook. Search engines typically provide two types of search results, natural (i.e., non-paid) and
purchased listings. Natural search results are determined and organized solely by automated criteria set by the search engine and a ranking level cannot be purchased. Advertisers can also pay search engines to place listings more prominently in
search results and websites in order to attract users to advertisers websites. To some extent, we rely on natural searches in order to attract free traffic to our website. Search engines revise their algorithms from time to time in an attempt
to optimize their search result listings. If search engines on which we rely for algorithmic listings modify their algorithms, our websites may appear less prominently or not at all in search results, which could result in fewer users clicking
through to our website. For example, in one instance in the past, traffic was mistakenly directed to one of our homepages that was not in the language of the search performed and resulted in lower users and premium subscriptions for that period.
Furthermore, competitors may in the future bid on our name from search services in an attempt to capture potential traffic. Preventing such actions and recapturing potential traffic could increase our expenses. Further, search engines or social
networking sites may change their policies from time to time regarding pay-per-click or other means of advertising. If any change to these policies delays or prevents us from advertising these through channels, this could result in fewer users
clicking through to our website.

We may face challenges expanding our premium subscription base and increasing revenues in emerging
markets due to difficulties in these markets associated with payment collections as well as legal, economic, tax and political risks that are greater than more developed markets.

Expanding our business into emerging markets is an important component of our growth strategy and presents challenges that are different
than those associated with more developed international markets. In particular, regulations limiting the use of local credit cards could constrain our growth in certain countries. For example, regulations in certain countries do not permit recurring
charges on credit cards. In the last quarter of 2011, we established a Brazilian subsidiary to process local credit cards in Brazil in compliance with Brazilian currency controls. It is often difficult to establish an effective local business model,
and we may need to enter into agreements with third-parties to process credit cards on our behalf or modify our business plans or operations in order to establish a local presence in emerging countries, which may delay our entry into these markets
or increase our costs. Additionally, in emerging markets we face the risk of more rapidly changing government policies and encountering sudden currency revaluations. It is possible that governments of one or more countries may censor or block access
to the Internet due to political concerns or in response to certain incidents or significant events, thereby preventing people in these countries, including our users, from accessing our products. The growth of our business may be adversely affected
if we are unable to expand our user base in emerging markets.

We face potential liability and expense for legal claims based on the
content on our platform.

Our platform allows users to create websites. At present, we do not require that our users
post on their websites, or require their visitors to agree to, any terms of service, privacy policy, disclaimer or any other contractual documentation or policy. If our users do not post or require agreement to the appropriate documentation and
policies on their websites, or should our users fail to take steps necessary to enjoy the benefits of certain statutory safe harbors, such as those set forth in Section 512 of the United States Copyright Act, then they may expose themselves to
civil and criminal liability under applicable law, for example, where the visitors post information which is libelous, defamatory, in breach of regulation concerning unacceptable content or publications, or in breach of any third-party intellectual
property rights or where our users or their suppliers fail to process personal data in accordance with applicable law. It is possible that we could also be subject to liability. In many jurisdictions, including the United States and countries in
Europe, laws relating to the liability of providers of online services for activities of their users and other third parties are currently being tested by a

number of claims, including actions based on defamation, invasion of privacy and other torts, unfair competition, copyright and trademark infringement, and other theories based on the nature and
content of the materials searched, the ads posted, or the content provided by users. Any court ruling or other governmental action that imposes liability on providers of online services for the activities of their users and other third parties could
harm our business. In such circumstances we may also be subject to liability under applicable law in a way which may not be fully mitigated by the user terms of service we require our users to agree to. Any liability attributed to us could adversely
affect our brand, reputation, our ability to expand our user base and our financial position. Further, our indemnity from the users may also not be fully effective as a matter of practice if any user does not have sufficient assets, insurance or
other means to back that indemnity. In addition, rising concern about the use of the Internet for illegal conduct, such as the unauthorized dissemination of national security information, money laundering or supporting terrorist activities may in
the future produce legislation or other governmental action that could require changes to our products, solutions or services, restrict or impose additional costs upon the conduct of our business or cause users to abandon material aspects of our
service. Any such adverse legal or regulatory developments could substantially harm our operating results and business.

Activities of
users or the content of their websites could damage our reputation and brand, or harm our ability to expand our base of users and premium subscriptions, and our business and financial results.

Our reputation and brand may be negatively affected by the actions of users that are deemed to be hostile, offensive or inappropriate to
other users, or by users acting under false or inauthentic identities. This particularly applies to our users who do not have premium subscriptions and who therefore maintain the Wix logo on their websites. We do not monitor or review
the appropriateness of the domain names our users register or the content of our users websites, and we do not have control over the activities in which our users engage. While we have adopted policies regarding illegal or offensive use of our
services by our users and retain authority to terminate domain name registrations and to take down websites that violate these policies, users could nonetheless engage in these activities. The safeguards we have in place may not be sufficient to
avoid harm to our reputation and brand, especially if such hostile, offensive or inappropriate use was high profile, which could adversely affect our ability to expand our user base, and our business and financial results.

We are exposed to risks associated with credit card and debit card payment processing.

We accept payments primarily through credit and debit card transactions and currently use an internal billing system, as well as
third-party billing systems that are integrated into our website and provide a portal for users to submit credit or debit card information for processing. We are subject to a number of risks related to credit and debit card payments, including:



we pay interchange and other fees, which may increase over time and could require us to either increase the prices we charge for our products or
experience an increase in our operating expenses;



if our billing systems fail to work properly and, as a result, we do not automatically charge our premium subscriptions credit cards on a timely
basis or at all, we could lose revenues; and



if we are unable to maintain our chargeback rate at acceptable levels, our credit card fees for chargeback transactions, or our fees for other credit
and debit card transactions or issuers, may increase, or issuers may terminate their relationship with us.

Our internal billing system interfaces with a number of different of gateway providers that link to a number of different payment card
processors based on the jurisdiction and other factors. In connection with this system, we have implemented data security standards, operating rules and certification requirements in accordance with Payment Card Industry, or PCI, Data Security
Standards in connection with internal controls requirements under Israeli law and we received PCI compliance level 1 certification in February 2013. There can be no assurance that our billing system data security standards, or those of our
third-party billing service providers, will adequately comply with the billing standards of any future jurisdiction in which we seek to market our service offering and establish a local billing solution.

If third-party applications change such that we do not or cannot maintain the compatibility of our
platform and solutions with these applications or if we fail to provide third-party applications that our users desire to add to their websites, demand for our solutions and platform could decline.

The attractiveness of our platform depends, in part, on our ability to integrate third-party applications which our users desire into
their websites. Third-party application providers may change the features of their applications and platforms or alter the terms governing use of their applications and platforms in an adverse manner. Further, third-party application providers may
refuse to partner with us, or limit or restrict our access to their applications and platforms. Such changes could functionally limit or terminate our ability to use these third-party applications and platforms with our platform, which could
negatively impact our offerings and harm our business. If we fail to integrate our platform with new third-party applications that our users need for their websites, or to adapt to the data transfer requirements of such third-party applications and
platforms, we may not be able to offer the functionality that our users expect, which would negatively impact our offerings and, as a result, harm our business.

Our business and prospects would be harmed if changes to technologies used in our solutions or new versions or upgrades of operating systems and Internet browsers adversely impact the process by
which users interface with our platform.

The user interface for our platform is currently simple and straightforward,
which we believe has helped us to expand our user base even among users with little technical expertise. In the future, Microsoft, the dominant operating system provider, or any other provider of Internet browsers, could introduce new features that
would make it difficult to use our platform. In addition, Internet browsers for desktop or mobile devices could introduce new features, or change existing browser specifications such that they would be incompatible with our products and solutions,
or prevent end users from accessing our users sites. For example, operating systems or major Internet browsers such as Firefox, Internet Explorer or Safari, could become unstable or be incompatible with HTML5-based products and solutions. Any
changes to technologies used in our solutions, including within operating systems or Internet browsers that make it difficult for users to access our platform or end-users to access our users sites, may slow the growth of our user base, and
adversely impact our business and prospects.

Our ability to enhance our products may be harmed if we are unable to attract and retain
sufficient research and development personnel.

In order to remain competitive, we must continue to develop new
solutions, applications and enhancements to our existing platform. Our principal research and development activities are conducted from our headquarters in Tel Aviv, Israel, and we face significant competition for suitably skilled developers in this
region. We also engage a small number of developers in the Ukraine through a third-party service organization in order to benefit from the significant pool of talent that is more readily available in that market. Many larger companies expend
considerably greater amounts on employee recruitment and may be able to offer more favorable compensation and incentive packages than us. If we cannot attract or retain sufficient skilled research and development employees, our business, prospects
and results of operations could be adversely affected.

Our future prospects may be adversely affected if we are unable to generate
revenues from sources other than our premium subscription packages.

In addition to our editor, we provide all of our
users with access to additional products and services that enhance their digital presence. For example, in the last quarter of 2012 we launched the Wix App Market, which is integrated into our platform. Through the App Market, we offer our users a
range of software applications that can be integrated as add-ons to their free or premium websites. The App Market offers both applications that are developed by us and by third-party developers. We cannot offer any assurances that sales of
applications or other value-added solutions and services we may offer in the future will be a significant part of our revenues. In addition, our selling efforts for these items may negatively impact our users perception of us due to our email
marketing to generate sales. If we do not succeed in selling these items, our future prospects may be adversely affected.

While there are other providers who offer features similar to those features found in our solutions, we believe that we do not compete
with traditional web development firms as we focus on not only web development but also technology, design and business work flow processes. Nevertheless, we do compete with aspects of the services provided by web-based website design platforms and
software programs, as well as some of the service offerings of a number of smaller template-based web builder companies and designers, as well as those who offer domain registration services, particularly using a freemium business model similar to
ours. In the future, we may experience increased competition from web design companies if they broaden their product and service offerings, or significantly lower their pricing. In addition, it is possible that other providers may in the future
decide that offering a platform similar to our platform represents an attractive business opportunity. In particular, if a more established company were to target our market, we may face significant competition from a company that enjoys potential
competitive advantages, such as greater name recognition, longer operating histories, substantially greater market share, larger existing user bases and substantially greater financial, technical and other resources. These companies may use these
advantages to offer solutions and service similar to ours at a lower price, develop different solutions to compete with our current solutions and respond more quickly and effectively than we do to new or changing opportunities, technologies,
standards or client requirements. Increased competition could result in us failing to attract users or obtain premium subscriptions at the same rate. It could also cause us to have higher acquisition costs or force us to lower our prices or take
other steps that may materially and adversely impact our results of operations.

If we fail to develop and introduce new products and
services and keep up with rapid changes in design and technology, our business may be materially and adversely affected.

Our future success will depend on our ability to improve the look, function, performance and reliability of our solutions and services,
including integrating Apps developed by third parties. The development of new and upgraded solutions and new service offerings involves a significant amount of time for our research and development team, as it can take our developers months to
update, code and test new and upgraded solutions and integrate them into our platform. Further, our design team spends a significant amount of time and resources in order to incorporate various design elements, such as customized colors, fonts,
content and other features into our new and upgraded solutions. The introduction of these new and upgraded design features, solutions and services also involves a significant amount of marketing spending. We must also manage our existing offerings,
as we continually test, support, and market these solutions and applications. Our revenues and competitive position could be materially and adversely affected if we fail to improve our design features or technology, or if our solutions fail to
achieve widespread acceptance.

Our corporate culture has contributed to our success, and if we cannot maintain this culture as we grow,
we could lose the innovation, creativity, and teamwork fostered by our culture, and our business may be harmed.

We
believe that an important contributor to our success has been our corporate culture, which we believe fosters innovation, teamwork, passion for our users, and a focus on attractive designs and technologically advanced products. Other than our
executive officers, as a result of our growth most of our employees have been with us for fewer than two years. As we continue to grow, we must effectively integrate, develop and motivate a growing number of new employees, including employees in
international markets. As a result, we may find it difficult to maintain important aspects of our corporate culture, which could limit our ability to innovate and operate effectively. Any failure to preserve our culture could also negatively affect
our ability to retain and recruit personnel, continue to perform at current levels or execute on our business strategy.

If we fail to
maintain a consistently high level of customer service, our brand, business and financial results may be harmed.

We
believe our focus on customer support is critical to retaining, expanding and further penetrating our user base. As a result, we have invested in the quality and training of our customer support and call center personnel. If we are unable to
maintain a consistently high level of customer service, we may lose existing users and find it more difficult to attract new users. In addition, regardless of the performance of our customer support and call

center, users of online services base their purchasing decisions on a number of factors, including price, design, integration abilities, functionality of services, reputation and ease of use. If
we fail to maintain adequate customer support which improves the functionality of our solutions and their ease of use, our reputation, financial results and business prospects may be harmed.

Our business relies on the experience and expertise of our senior management.

The success of our business is dependent to a large degree on the continued service of our executive officers. If we lose the services of any of our key personnel and fail to manage a smooth transition to
new personnel, our business could suffer. We do not carry key person insurance on any of our executive officers or other key personnel. We have entered into employment and services agreements with our executive officers and key employees that
contain non-compete covenants. Despite these agreements, we may not be able to retain these officers and employees. If we cannot enforce the non-compete covenants, we may be unable to prevent our competitors from benefiting from the expertise of our
former employees, which could materially and adversely affect our business and results of operations.

Our revenues may not increase if
we are unable to maintain market share for mobile sites and applications, or if our mobile products fail to achieve widespread acceptance, which may affect our business and future prospects.

Consumers are increasingly accessing the Internet through devices other than personal computers, including mobile phones, smartphones and
tablets. This trend has increased dramatically in the past few years and is projected to continue to increase. Acknowledging this trend, we launched our first free mobile offering in 2011, offering our users the ability to quickly and easily deploy
an HTML5 mobile-optimized website. The mobile device market is characterized by the frequent introduction of new products and solutions, short product life cycles, evolving industry standards, continuous improvement in performance characteristics
and rapid adoption of technological and product advancements. We may incur additional costs in order to adapt our current functionalities to other operating systems and we may face technical challenges adapting our products to different versions of
already supported operating systems, such as Android variants offered by different mobile phone manufacturers. If we are unable to offer continual improvements to our mobile solutions or adapt their functionalities to new and different operating
systems, our mobile solutions may fail to achieve widespread acceptance by our users. Additionally, the providers of certain platforms, such as Apple, may limit or restrict access entirely to their platforms. Therefore, our revenues may not increase
even if we continue to penetrate the mobile device market.

Our results of operations and cash flows are affected by fluctuations due to changes in foreign currency exchange
rates. In 2012, 89% of our revenues were denominated in U.S. dollars and 11% in other currencies, primarily in euros. Conversely, in 2012, 58% of our cost of revenues and operating expenses were denominated in U.S. dollars and 42% in New Israeli
Shekels, or NIS. Our NIS-denominated expenses consist primarily of personnel and overhead costs. Since a significant portion of our expenses are denominated in NIS, any appreciation of the NIS relative to the U.S. dollar would adversely impact our
net loss or net income (if any). We estimate that a 10% increase (decrease) in the value of the NIS against the U.S. dollar would have decreased (increased) our net income by approximately $2.5 million in 2012. To protect against the increase in
value of forecasted foreign currency cash flow resulting from expenses paid in NIS during the year, we have instituted a foreign currency cash flow hedging program. We hedge portions of the anticipated payroll of our Israeli employees, Israeli
suppliers and anticipated rent expenses of our Israeli premises denominated in NIS for a period of one to twelve months with forward contracts and other derivative instruments. We cannot provide any assurances that our hedging activities will be
successful in protecting us from adverse impacts from currency exchange rate fluctuations. See Managements Discussion and Analysis of Financial Condition and Results of OperationsQuantitative and Qualitative Disclosure About Market
RiskForeign Currency Risk.

Because we recognize revenues from premium subscriptions over the term of an agreement, downturns or
upturns in sales are not immediately reflected in full in our operating results.

We recognize revenues over the term
of our contracts. During the six months ended June 30, 2013, approximately 59% of our premium subscription revenues were from annual subscriptions and approximately 41% were from monthly subscriptions. As a result, much of the revenue we report each
quarter is the recognition of deferred revenue from premium subscriptions entered into during previous quarters. Consequently, a shortfall in demand for our solutions and services or a decline in new or renewed contracts in any one quarter may not
significantly reduce our revenues for that quarter but could negatively affect our revenues in future quarters. Accordingly, the effect of significant downturns in new or renewed sales of our solutions and service offerings are not reflected in full
in our results of operations until future periods.

The impact of worldwide economic conditions, including the resulting effect on
spending by small to medium-sized businesses, may adversely affect our business, operating results and financial condition.

Our performance is subject to worldwide economic conditions and their impact on levels of spending by small and medium-sized businesses, which may be disproportionately affected by economic downturns. To
the extent that worldwide economic conditions materially deteriorate, our existing and potential premium subscriptions may no longer consider investment in our solutions and platform a necessity, or may elect to reduce budgets for maintaining a
digital presence. Economic conditions may adversely impact levels of user spending, which could adversely impact the numbers of users visiting our website. User purchases of discretionary items generally decline during recessionary periods and other
periods in which disposable income is adversely affected, which could have a material adverse effect on our financial condition and results of operations.

Our business will suffer if the small business market for our solutions proves less lucrative than projected or if we fail to effectively acquire and service small business users.

We market and develop solutions for small businesses and a majority of our premium subscriptions are from small
businesses. Small businesses frequently have limited budgets and may choose to allocate resources to items other than our solutions, especially in times of economic uncertainty or recessions. We believe that the small business market is underserved,
and we intend to continue to devote substantial resources to it. We aim to grow our revenues by adding new small business customers, selling additional services to existing small business customers and encouraging existing small business customers
to renew their subscriptions to our premium solutions. If the small business market fails to be as lucrative as we project or we are unable to market and sell our services to small businesses effectively, our ability to grow our revenues quickly and
become profitable will be harmed.

We are subject to trade and economic sanctions and export laws that may govern or restrict our
business and we, and our directors and officers, may be subject to fines or other penalties for non-compliance with those laws.

U.S. Laws and Regulations

We are subject to
U.S. laws and regulations that may govern or restrict our business and activities in certain countries and with certain persons, including the trade and economic sanctions regulations administered by the U.S. Treasury Departments Office of
Foreign Assets Control, or OFAC, and the export administration regulations administered by the U.S. Commerce Departments Bureau of Industry and Security, or BIS. In the course of an internal review in early 2013, we determined that we had 16
premium subscriptions, out of a total of approximately 583,000 premium subscriptions, with geographic internet protocols, or GEOIP, addresses in Cuba, Iran, North Korea, North Sudan or Syria (U.S. Sanctioned Countries) or that had
otherwise provided personal information indicating that they may be located in U.S. Sanctioned Countries. As part of a subsequent internal review, we also determined that we had 32,600 users, or less than 0.1% of our total user base of approximately
33 million as measured as of April 30, 2013, with GEOIP addresses in U.S. Sanctioned Countries.

In May 2013, we made a
voluntary self-disclosure to OFAC and BIS. We cannot predict when OFAC and BIS will complete their respective reviews and determinations as to whether any violation of relevant U.S. sanctions or export laws occurred or is ongoing. In case of an
apparent violation, OFAC and/or BIS could decide

not to impose penalties but issue only a warning or cautionary letter. However, if OFAC or BIS determines that we have violated applicable regulations, we may face civil and/or criminal penalties
and may also suffer reputational harm, any of which could have a material adverse effect on our business and financial results.

We have undertaken a number of remedial measures, including terminating the users and the premium subscriptions that may have been from a
U.S. Sanctioned Country, and blocking the ability of new users  with or without a premium subscription  that have a GEOIP address in a U.S. Sanctioned Country to access our cloud-based software or services. We have also since instituted
new periodic screening practices and updated our systems to prevent users from U.S. Sanctioned Countries entering billing information with an address in that location. We are working to implement other measures related to our billing practices.

Israeli Laws and Regulations

The Israeli Trading with the Enemy Ordinance - 1939 (the Ordinance) prohibits any Israeli person from trading goods with enemy countries or with the residents of enemy countries. The Israeli
Ministry of Finance, which is responsible for implementing the Ordinance, has currently determined enemy countries to be Iran, Lebanon and Syria (Israeli Sanctioned Countries). The Ordinance was enacted in 1939 and does not expressly
address online services. We therefore cannot state with certainty how the provisions of the Ordinance apply to the type of services that we provide.

We voluntarily approached the Israeli Ministry of Finance in September 2013 and asked for its formal position regarding the applicability of the Ordinance to the type of services that we provide. We do
not know the extent to which the Ministry of Finance will want to have further discussions with us, the timing of those discussions or the ultimate outcome of their deliberations. Although the Ordinance allows Israeli persons to apply for a permit
to trade with Israeli Sanctioned Countries or their residents, we are not aware of a permit being granted or denied in the past to a person providing the type of services that we provide.

Lebanon is the only Israeli Sanctioned Country that is not also a U.S. Sanctioned Country. We have ceased providing services to users with
a GEOIP address in a U.S. Sanctioned Country. The number of users and premium subscribers that we have in Lebanon is not material to our business, however, if we stop providing services in Lebanon, it may decrease the number of our current and
future subscribers from other countries, particularly in the Middle East, who may cease using our services in protest to us blocking accounts in Israeli Sanctioned Countries.

In addition, if it is determined by a competent court that sanctions under the Ordinance cover the type of services that we provide, we, our officers and employees may be subject to criminal and/or civil
actions. We believe that our initiation of voluntary discussions with the Israeli Ministry of Finance may reduce such exposure, but any liability to which we are subject to could adversely affect our personnel, brand and reputation.

We are subject to privacy and data protection laws and regulations as well as contractual privacy and data protection obligations, and our failure
to comply with these or any future laws, regulations, or obligations could subject us to sanctions and damages and could harm our reputation and business.

We hold certain personal data of our users, primarily, username and email address, and may hold certain personal data of the visitors to our users websites. We have implemented data security
standards, operating rules and certification requirements in accordance with PCI Data Security Standards and we received PCI compliance level 1 certification in February 2013. Since we began using our internal billing system in the first quarter of
2013, we have begun to also collect billing information, such as credit card numbers, full names, billing address and phone numbers in compliance with these data security standards. We do not regularly monitor or review the content that our users
upload and store and, therefore, do not control the substance of the content within our hosted environment, including sensitive personal information.

We are subject to the privacy and data protection laws and regulations adopted by Israel and potentially, other jurisdictions. For example, although we do not have an operating entity in the Netherlands,
the control that we exert over our servers in the Netherlands may result in our activities in Europe being deemed to be subject to Dutch law. Where the local data protection and privacy laws of a jurisdiction apply, we may be required to

register our operations in that jurisdiction or make changes to our business so that user data is only collected and processed in accordance with applicable local law. Privacy laws restrict our
storage, use, processing, disclosure, transfer and protection of personal information, including credit card data, provided to us by our users, and possibly the visitors to our users websites. We strive to comply with all applicable laws,
regulations, policies and legal obligations, as well as with certain industry standards (including voluntary third-party certification bodies such as TRUSTe) relating to privacy and data protection. We are also subject to the privacy and data
security-related obligations set forth in our terms of use with our users, and we may be liable to third parties in the event we are deemed to have wrongfully processed personal data.

The regulatory framework for privacy and data security issues worldwide is currently in flux and is likely to remain so for the
foreseeable future. In particular, the European Union has traditionally taken a broader view as to what is considered personal information and has imposed greater obligations under their privacy and data protection laws. For example, the European
Union issued a proposal for a new General Data Protection Regulation at the beginning of 2012 which will replace the European Data Protection Directive and is likely to include more stringent obligations for online businesses, such as to conduct a
data protection impact assessment for certain higher-risk processing operations, to introduce a more frequent need for the users consent, to impose an obligation to act on data breaches, to restrict the collection and use of
sensitive personal data and to expand the legislative requirements for data processors, as well as to introduce a stricter regime of enforcement. Additionally, the proposed regulation is stated to have extra-territorial effect and seeks
to regulate the European activities of businesses regardless of their location or the locations of their servers. While it is currently expected that the proposed regulation will not take effect until 2015 or later, the more stringent requirements
on privacy user notifications and data handling will require us to adapt our business and are likely to incur additional cost should we become subject to these and other laws and regulations, which could force us to incur material costs of require
us to adapt our business.

A failure by us or a third-party contractor providing services to us to comply with applicable
privacy and data security laws, regulations, self-regulatory requirements or industry guidelines, or our terms of use with our users, may result in sanctions, statutory or contractual damages or litigation. These proceedings or violations could
force us to spend money in defense or settlement of these proceedings, result in the imposition of monetary liability, incur additional management resource, increase our costs of doing business, and adversely affect our reputation and the demand for
our solutions.

If the security of the confidential information or personal information of our users and the visitors to our users
websites stored in our systems is breached or otherwise subjected to unauthorized access, our reputation may be harmed and we may be exposed to liability.

Due to the nature of our business, our system stores personally identifiable information, credit card information and other critical data for our users and the visitors of our users websites. We
believe that we take reasonable steps to protect the security, integrity and confidentiality of the information we collect and store, but there is no guarantee that inadvertent (e.g., software bugs or other technical malfunctions, employee error or
malfeasance, or other factors) or unauthorized disclosure will not occur or that third parties will not gain unauthorized access to this information despite our efforts. Like many online companies, we have experienced attempts by third parties to
circumvent the security of our systems but are not aware of any successful attempts. We may in the future experience successful attempts by third parties to obtain unauthorized access to our data despite our security measures. Since techniques used
to obtain unauthorized access change frequently, we may be unable to anticipate these techniques or to implement adequate preventative measures. If our security measures are breached because of third-party action, employee error, malfeasance or
otherwise, or if design flaws in our software are exposed and exploited, and, as a result, a third party obtains unauthorized access to any of our users data, our relationships with our users may be damaged, and we could incur liability. In
addition, some jurisdictions have enacted laws requiring companies to notify individuals of data security breaches involving certain types of personal data, and our agreements with certain partners require us to notify them in the event of a
security incident. These mandatory disclosures regarding a security breach sometimes lead to negative publicity and may cause our users to lose confidence in the effectiveness of our data security measures. Any security breach, whether actual or
perceived, may harm our reputation, and we could lose users or fail to acquire new users.

If our security measures fail to protect credit card information adequately, we could be
liable to both our users for their losses, as well as the vendors under our agreements with them such that we could be subject to fines and higher transaction fees, we could face regulatory action, and our users and vendors could end their
relationships with us, any of which could harm our business, results of operations or financial condition. Any willful or accidental security breaches or other unauthorized access or unlawful processing could expose us to liability for the loss of
such information, adverse regulatory action by governments in the United States, Israel, and elsewhere, investigation and litigation, downtime of our systems and other possible liabilities. There can be no assurance that the limitations of liability
in our contracts would be enforceable or adequate or would otherwise protect us from any such liabilities or damages with respect to any particular claim. We also cannot assure you that our existing general liability insurance coverage and coverage
for errors and omissions will continue to be available on acceptable terms or will be available in sufficient amounts to cover one or more large claims, or that the insurer will not deny coverage as to any future claim. The successful assertion of
one or more large claims against us that exceeds available insurance coverage, or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could have a
material adverse effect on our business, financial condition and results of operations.

We are subject to the rules and regulations
adopted by the payment card networks, such as Visa and MasterCard, and if we fail to adhere to their rules and regulations, we would be in breach of our contractual obligations to payment processors and merchant banks, which could subject us to
damages and liability and could eventually prevent us from processing or accepting credit card payments.

The payment
card networks, such as Visa and MasterCard have adopted rules and regulations that apply to all merchants who process and accept credit cards for payment of goods and services. We are obligated to comply with these rules and regulations as part of
the contracts we enter into with payment processors and merchant banks. The rules and regulations adopted by the payment card networks include the Payment Card Industry Data Security Standards, or PCI DSS. Under the PCI DSS, we are required to adopt
and implement internal controls over the use, storage and security of payment card data to help prevent fraud. If we fail to comply with the rules and regulations adopted by the payment card networks, including the PCI DSS, we would be in breach of
our contractual obligations to payment processors and merchant banks. Such failure to comply may subject us to fines, penalties, damages, higher transaction fees, and civil liability, and could eventually prevent us from processing or accepting
debit and credit cards or could lead to a loss of payment processor partners. We also cannot guarantee that such compliance will prevent illegal or improper use of our payments systems or the theft, loss or misuse of the debit or credit card data of
users or participants or regulatory or criminal investigations. A failure to adequately control fraudulent credit card transactions would result in significantly higher credit card-related costs and any increases in our credit card and debit card
fees could adversely affect our results of operations. Moreover, any such illegal or improper payments could harm our reputation and may result in a loss of service for our users, which would adversely affect our business, operating results and
financial condition.

We may be unable to obtain, maintain and protect our intellectual property rights and proprietary information or
prevent third parties from making unauthorized use of our technology.

Our intellectual property rights are important
to our business. We rely on a combination of confidentiality clauses, trade secrets, copyrights and trademarks to protect our intellectual property and know-how. In addition, we have filed a number of applications for patents to protect our
technologies. However, the steps we take to protect our intellectual property may be inadequate. We will not be able to protect our intellectual property if we are unable to enforce our rights or if we do not detect unauthorized use of our
intellectual property. Despite our precautions, it may be possible for unauthorized third parties to copy our products and use information that we regard as proprietary to create solutions and services that compete with ours. Some license provisions
protecting against unauthorized use, copying, transfer and disclosure of our solutions may be unenforceable under the laws of certain jurisdictions and foreign countries.

We enter into confidentiality and invention assignment agreements with our employees and consultants and enter into confidentiality agreements with the parties with whom we have strategic relationships
and business

alliances. No assurance can be given that these agreements will be effective in controlling access to our proprietary information. Further, these agreements do not prevent our competitors from
independently developing technologies that are substantially equivalent or superior to our solutions. Additionally, we may from time to time be subject to opposition or similar proceedings with respect to applications for registrations of our
intellectual property, including but not limited to our trademarks and patent applications. While we aim to acquire adequate protection of our brand through trademark registrations in key markets, occasionally third parties may have already
registered or otherwise acquired rights to identical or similar marks for solutions that also address the software market. Additionally, the process of seeking patent protection can be lengthy and expensive. Any of our pending or future patent or
trademark applications, whether or not challenged, may not be issued with the scope of the claims we seek, if at all. We are unable to guarantee that additional patents or trademarks will issue from pending or future applications or that, if patents
or trademarks issue, they will not be challenged, invalidated or circumvented, or that the rights granted under the patents will provide us with meaningful protection or any commercial advantage. We rely on our brand and trademarks to identify our
solutions to our users and to differentiate our solutions from those of our competitors, if we are unable to adequately protect our trademarks, third parties may use our brand names or trademarks similar to ours in a manner that may cause confusion
to our users or confusion in the market, or dilute our brand names or trademarks, which could decrease the value of our brand.

From time to time, we may discover that third parties are infringing, misappropriating or otherwise violating our intellectual property
rights. However, policing unauthorized use of our intellectual property and misappropriation of our technology is difficult and we may therefore not always be aware of such unauthorized use or misappropriation. Despite our efforts to protect our
intellectual property rights, unauthorized third parties may attempt to use, copy or otherwise obtain and market or distribute our intellectual property rights or technology or otherwise develop solutions with the same or similar functionality as
our solutions. If competitors infringe, misappropriate or otherwise misuse our intellectual property rights and we are not adequately protected, or if such competitors are able to develop solutions with the same or similar functionality as ours
without infringing our intellectual property, our competitive position and results of operations could be harmed and our legal costs could increase.

We are subject to claims by third parties of intellectual property infringement and may in the future become subject to additional claims that, regardless of merit, could result in litigation and
materially adversely affect our business, results of operations or financial condition.

There can be no assurance that
third parties will not assert that our solutions, services and intellectual property infringe, misappropriate or otherwise violate their intellectual property or other proprietary rights. Such claims may be made by competitors seeking to obtain a
competitive advantage or by other parties. Additionally, in recent years, non-practicing entities, or NPEs, have begun purchasing intellectual property assets for the purpose of making claims of infringement and attempting to extract settlements
from companies like ours.

For example, we are currently subject to a patent infringement litigation that was filed against us
on December 7, 2012 by CreateAds LLC, an entity that we believe is an NPE. The complaint alleges that we infringe a U.S. patent owned by CreateAds LLC. CreateAds LLC has filed similar complaints alleging infringement against at least forty
other defendants. We filed a motion to dismiss the complaint in its entirety on February 1, 2013, on the grounds that the patent-in-suit claims only abstract ideas. On February 25, 2013, the plaintiff opposed our motion and on
March 14, 2013 we filed a reply in support of the motion. We intend to continue pursuing the dismissal of the case. Due to the early stage of the proceedings, we currently do not have the ability to assess the probability of a particular
outcome or the potential exposure from this lawsuit. We also recently entered into a settlement agreement with another NPE with respect to a claim that we infringed its patent. See BusinessLegal Proceedings.

Any such claims, regardless of merit, that result in litigation, could result in substantial expenses, divert the attention of management,
cause significant delays in introducing new solutions or services, materially disrupt the conduct of our business and have a material and adverse effect on our brand, reputation, business, financial

condition and results of operations. As a consequence of such claims, we could be required to pay substantial damages, develop non-infringing technology, enter into royalty-bearing licensing
agreements, stop selling or marketing some or all of our solutions or services or re-brand our solutions or services. If it appears necessary, we may seek to license intellectual property that we are alleged to infringe, potentially even if we
believe such claims to be without merit. If required licenses cannot be obtained, or if existing licenses are not renewed, litigation could result. Litigation is inherently uncertain and any adverse decision could result in a loss of our proprietary
rights, subject us to significant liabilities, require us to seek licenses for alternative technologies from third parties and otherwise negatively affect our business.

We use open source software in connection with our software development. From time to time, companies that use open source software have
faced claims challenging the use of open source software and/or compliance with open source license terms, and we may be subject to such claims in the future. Some open source licenses require users who distribute software containing open source to
make available all or part of such software, which in some circumstances could include valuable proprietary code of the user. While we monitor the use of open source software and try to ensure that none is used in a manner that would require us to
disclose our proprietary source code or that would otherwise breach the terms of an open source agreement, it is our view that we do not distribute our software, since no installation of our software is necessary and editing and design platform is
accessible solely through the cloud. Nevertheless, this position could be challenged. Any requirement to disclose our proprietary source code or pay damages for breach of contract could be harmful to our business, results of operations
or financial condition, and could help our competitors develop products and services that are similar to or better than ours.

The
number of our registered users may be higher than the number of actual users, and we have no means of assessing the level of engagement of a particular user following registration.

We use the definition user to mean the number of unique email addresses registered on Wix.com. The number of users as we
define it may be higher than the actual number of users because some users have multiple registrations and others may have registered under different or fictitious names. In addition, we have no means of assessing the level of engagement of a
particular user following registration. The length of time that users take following registration to design and publish a website varies significantly from hours to years. Some users may never publish a website, but have not cancelled their
registration. Even if it were measurable, we do not consider the level of engagement of our registered users to be material to our business. Rather, we consider the rate at which users from a particular period generate premium subscriptions to be
material to our business. For example, in the second quarter of 2013, 43% of our premium subscriptions were purchased by users that registered with us in the same quarter and the remaining 57% were from users who registered in earlier quarters.
Nevertheless, if the number of our registered users is materially inconsistent with the number of our actual users, our user base, which we believe is important to the growth of our premium subscriptions, may be overstated. If that is the case, our
business may not grow as fast as we expect, and our financial results and business prospects may be harmed.

We may become subject to
claims for remuneration or royalties for assigned service invention rights by our contractors or employees, which could result in litigation and adversely affect our business.

We enter into assignment of invention agreements with certain of our employees pursuant to which such individuals agree to assign to us
all rights to any inventions created in the scope of their employment or engagement with us. Under the Israeli Patent Law, inventions conceived by an employee or a person deemed to be an employee during the scope of their employment with a company
are regarded as service inventions, which belong to the employer, absent a specific agreement between employee and employer giving the employee service invention rights. The Patent Law also provides that if there is no such agreement
between an employer and an employee, the Israeli Compensation and Royalties Committee shall determine whether the employee or contractor is entitled to remuneration for their inventions. However, recent decisions by the Israeli Compensation

and Royalties Committee and the Supreme Court have created uncertainty in this area, as the Supreme Court held that employees may be entitled to remuneration for their service inventions despite
having specifically waived such rights. Further, the Committee has not yet determined the method for calculating this Committee-enforced remuneration. Although our contractors or employees have agreed to assign to us service invention rights, we may
face claims challenging such agreements and demanding remuneration in consideration for assigned inventions. As a consequence of such claims, we could be required to pay additional remuneration or royalties to our contractors or employees, or be
forced to litigate such claims, which could otherwise negatively affect our business.

U.S. states may seek to impose state and local
business taxes and sales/use taxes and current EU taxes on Internet sales may increase.

There is a risk that U.S.
states could assert that we or our non-U.S. subsidiaries are liable for U.S. state and local business activity taxes based upon income or gross receipts or for the collection of U.S. local sales/use taxes. This risk exists regardless of whether we
and our non-U.S. subsidiaries are subject to U.S. federal income tax. States are becoming increasingly aggressive in asserting a nexus for business activity tax purposes and imposing sales/use taxes on products and services provided over the
Internet. We and our non-U.S. subsidiaries could be subject to U.S. state and local taxation if a state tax authority asserts that our activities or the activities of our non-U.S. subsidiaries give rise to a nexus. We and our non-U.S. subsidiaries
could also be liable for the collection of U.S. state and local sales/use taxes if a state tax authority asserts that distribution of our products over the Internet is subject to sales/use taxes. Additionally, pending legislation in the U.S.
Congress, if enacted, could grant states additional authority to collect sales/use taxes on the sale of our premium subscriptions over the Internet. Further, if a state tax authority asserts that distribution of our products or services is subject
to such sales/use taxes, our premium subscribers could also be subjected to sales/use taxes, which may decrease the likelihood that such users would purchase or continue to renew their premium subscriptions. Additionally, sales of our solutions
subject to value-added tax, or VAT, at the applicable rate in each jurisdiction, which may increase and cause either our prices to increase or our revenues to decline. New obligations to collect or pay taxes of any kind could substantially increase
our cost of doing business.

We may need to raise additional funds to pursue our growth strategy or continue our operations, and we may
be unable to raise capital when needed or on acceptable terms.

From time to time, in addition to this offering, we may
seek additional equity or debt financing to fund our growth, develop new solutions and services or make acquisitions or other investments. Our business plans may change, general economic, financial or political conditions in our markets may change,
or other circumstances may arise, that have a material adverse effect on our cash flow and the anticipated cash needs of our business. Any of these events or circumstances could result in significant additional funding needs, requiring us to raise
additional capital. We cannot predict the timing or amount of any such capital requirements at this time. If financing is not available on satisfactory terms, or at all, we may be unable to expand our business or to develop new business at the rate
desired and our results of operations may suffer.

We may make acquisitions and investments, which could result in operating
difficulties, dilution and other harmful consequences.

From time to time, we evaluate potential strategic acquisition
or investment opportunities. Any transactions that we enter into could be material to our financial condition and results of operations. The process of integrating an acquired company, business or technology could create unforeseen operating
difficulties and expenditures. Acquisitions and investments carry with them a number of risks, including the following:



diversion of management time and focus from operating our business;



implementation or remediation of controls, procedures and policies of the acquired company;



coordination of product, engineering and selling and marketing functions;

litigation or other claims arising in connection with the acquired company; and



in the case of foreign acquisitions, the need to integrate operations across different cultures and languages and to address the particular economic,
currency, political and regulatory risks associated with specific countries.

Our failure to address these
risks or other problems encountered in connection with acquisitions and investments could cause us to fail to realize the anticipated benefits of such acquisitions or investments, incur unanticipated liabilities and harm our business, results of
operations and financial condition.

Risks Related to Our Ordinary Shares and the Offering

Our share price may be volatile, and you may lose all or part of your investment.

The initial public offering price for the ordinary shares sold in this offering will be determined by negotiation between us and
representatives of the underwriters. This price may not reflect the market price of our ordinary shares following this offering and the price of our ordinary shares may decline. In addition, the market price of our ordinary shares could be highly
volatile and may fluctuate substantially as a result of many factors, including:



actual or anticipated fluctuations in our results of operations;



variance in our financial performance from the expectations of market analysts;



announcements by us or our competitors of significant business developments, changes in service provider relationships, acquisitions or expansion
plans;



changes in the prices of our solutions;



our involvement in litigation;



our sale of ordinary shares or other securities in the future;



market conditions in our industry;



changes in key personnel;



the trading volume of our ordinary shares;



changes in the estimation of the future size and growth rate of our markets; and



general economic and market conditions.

In addition, the stock markets have experienced extreme price and volume fluctuations. Broad market and industry factors may materially harm the market price of our ordinary shares, regardless of our
operating performance. In the past, following periods of volatility in the market price of a companys securities, securities class action litigation has often been instituted against that company. If we were involved in any similar litigation
we could incur substantial costs and our managements attention and resources could be diverted.

There has been no prior public
market for our ordinary shares, and an active trading market may not develop.

Prior to this offering, there has been
no public market for our ordinary shares. An active trading market may not develop following completion of this offering or, if developed, may not be sustained. The lack of an active market may impair your ability to sell your shares at the time you
wish to sell them or at a price that you consider reasonable. The lack of an active market may also reduce the fair market value of your shares. An inactive market may also impair our ability to raise capital by selling shares of capital stock and
may impair our ability to acquire other companies by using our shares as consideration.

If we do not meet the expectations of equity research analysts, if they do not publish research or
reports about our business or if they issue unfavorable commentary or downgrade our ordinary shares, the price of our ordinary shares could decline.

The trading market for our ordinary shares will rely in part on the research and reports that equity research analysts publish about us and our business. The analysts estimates are based upon their
own opinions and are often different from our estimates or expectations. If our results of operations are below the estimates or expectations of public market analysts and investors, our stock price could decline. Moreover, the price of our ordinary
shares could decline if one or more securities analysts downgrade our ordinary shares or if those analysts issue other unfavorable commentary or cease publishing reports about us or our business.

Following the closing of this offering, a small number of significant beneficial owners of our shares acting together will have a controlling
influence over matters requiring shareholder approval, which could delay or prevent a change of control.

Following the
closing of this offering, the largest beneficial owners of our shares, entities and individuals affiliated with Mangrove Capital Partners, Bessemer Venture Partners, Insight Venture Partners, and Benchmark Capital Partners, each of which currently
beneficially owns more than 10.0% of our outstanding shares, will beneficially own in the aggregate % of our ordinary shares or % if the underwriters
exercise their option to purchase additional ordinary shares. As a result, these shareholders, acting together, could exercise a controlling influence over our operations and business strategy and will have sufficient voting power to control the
outcome of matters requiring shareholder approval. These matters may include:



the composition of our board of directors which has the authority to direct our business and to appoint and remove our officers;



approving or rejecting a merger, consolidation or other business combination;

This concentration of ownership of our ordinary shares could delay or prevent proxy contests, mergers, tender offers, open-market purchase
programs or other purchases of our ordinary shares that might otherwise give you the opportunity to realize a premium over the then-prevailing market price of our ordinary shares. This concentration of ownership may also adversely affect our share
price.

As a foreign private issuer, we may follow certain home country corporate governance practices instead of certain New York Stock
Exchange, or NYSE, corporate governance requirements.

As a foreign private issuer, in reliance on Section 303A.11 of
the NYSE Listed Company Manual, which permits a foreign private issuer to follow the corporate governance practices of its home country, we will be permitted to follow certain Israeli corporate governance practices instead of those otherwise
required under the corporate governance standards for U.S. domestic issuers. As of the consummation of this offering, we intend to follow the NYSE corporate governance standards for domestic issuers. We may in the future elect to follow home country
practice in Israel with regard to matters such as the formation of compensation, nominating and corporate governance committees, separate executive sessions of independent directors and non-management directors and the requirement to obtain
shareholder approval for certain dilutive events (such as for the establishment or amendment of certain equity-based compensation plans, issuances that will result in a change of control of the company, certain transactions other than a public
offering involving issuances of a 20% or more interest in the company and certain acquisitions of the stock or assets of another company). Accordingly, our shareholders may not be afforded the same protection as provided under NYSE corporate
governance rules. Following our home country governance practices as opposed to the requirements that would otherwise apply to a United States company listed on the NYSE may provide less protection than is accorded to investors of domestic issuers.
See ManagementCorporate Governance Practices.

As a foreign private issuer we will not be subject to U.S. proxy rules and will be exempt from filing
certain Exchange Act reports.

As a foreign private issuer, we will be exempt from the rules and regulations under the
United States Securities Exchange Act of 1934, as amended, or the Exchange Act, related to the furnishing and content of proxy statements, and our officers, directors, and principal shareholders will be exempt from the reporting and short-swing
profit recovery provisions contained in Section 16 of the Exchange Act. We will also be exempt from Regulation FD, which prohibits issuers from making selective disclosures of material non-public information. In addition, we will not be
required under the Exchange Act to file annual, quarterly and current reports and financial statements with the Securities and Exchange Commission, or SEC, as frequently or as promptly as domestic companies whose securities are registered under the
Exchange Act.

In addition, we would lose our foreign private issuer status if a majority of our directors or executive
officers are U.S. citizens or residents and we fail to meet additional requirements necessary to avoid loss of foreign private issuer status. Although we have elected to comply with certain U.S. regulatory provisions, our loss of foreign private
issuer status would make such provisions mandatory. The regulatory and compliance costs to us under U.S. securities laws as a U.S. domestic issuer may be significantly higher. If we are not a foreign private issuer, we will be required to file
periodic reports and registration statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive than the forms available to a foreign private issuer. We may also be required to modify certain of our policies to comply
with good governance practices associated with U.S. domestic issuers. Such conversion and modifications will involve additional costs. In addition, we may lose our ability to rely upon exemptions from certain corporate governance requirements on
U.S. stock exchanges that are available to foreign private issuers.

We are an emerging growth company and we cannot be
certain whether the reduced requirements applicable to emerging growth companies will make our ordinary shares less attractive to investors.

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 effective on April 5, 2012, or the JOBS Act, and we may take advantage of certain
exemptions from various requirements that are applicable to other public companies that are not emerging growth companies. Most of such requirements relate to disclosures that we would only be required to make if we cease to be a foreign
private issuer in the future. Nevertheless, as a foreign private issuer that is an emerging growth company, we will not be required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, or the
Sarbanes-Oxley Act, for up to five fiscal years after the date of this offering. We will remain an emerging growth company until the earliest of: (a) the last day of our fiscal year during which we have total annual gross revenues of at least
$1.0 billion; (b) the last day of our fiscal year following the fifth anniversary of the completion of this offering; (c) the date on which we have, during the previous three-year period, issued more than $1.0 billion in non-convertible
debt; or (d) the date on which we are deemed to be a large accelerated filer under the Exchange Act. When we are no longer deemed to be an emerging growth company, we will not be entitled to the exemptions provided in the JOBS Act
discussed above. We cannot predict if investors will find our ordinary shares less attractive as a result of our reliance on exemptions under the JOBS Act. If some investors find our ordinary shares less attractive as a result, there may be a less
active trading market for our ordinary shares and our share price may be more volatile.

The market price of our ordinary shares could
be negatively affected by future sales of our ordinary shares.

After this offering, there will
be shares of our ordinary shares outstanding. Sales by us or our shareholders of a substantial number of ordinary shares in the public market following
this offering, or the perception that these sales might occur, could cause the market price of our ordinary shares to decline or could impair our ability to raise capital through a future sale of, or pay for acquisitions using, our equity
securities. Of our issued and outstanding shares, all the ordinary shares sold in this offering will be freely transferable, except for any shares acquired by our affiliates, as that term is defined in Rule 144 under the U.S. Securities
Act of 1933. Following completion of this offering, % of our outstanding ordinary shares (or % if the underwriters exercise their option in full) will be
considered restricted shares and will be held by our affiliates.

Such securities can be resold into the public markets in the future in accordance with the requirements of Rule 144, including volume limitations, manner of sale requirements and notice
requirements. See Shares Eligible for Future Sale.

We, our executive officers and directors, and the holders of
substantially all of our outstanding ordinary shares, have agreed with the underwriters that, subject to limited exceptions, for a period of 180 days after the date of this prospectus, we and they will not directly or indirectly offer, pledge, sell,
contract to sell, grant any option to purchase or otherwise dispose of any ordinary shares or any securities convertible into or exercisable or exchangeable for ordinary shares, or in any manner transfer all or a portion of the economic consequences
associated with the ownership of ordinary shares, or cause a registration statement covering any ordinary shares to be filed except for the ordinary shares offered in this offering, without the prior written consent of the designated representatives
of the underwriters, who may, in their sole discretion and at any time without notice, release all or any portion of the shares subject to these lock-up agreements.

Starting six months after the closing of this offering, all of our shareholders prior to this offering are entitled to require that we register their shares under the U.S. Securities Act of 1933 for
resale into the public markets. All shares sold pursuant to an offering covered by such registration statement will be freely transferable. See Certain Relationships and Related Party TransactionsRegistration Rights.

In addition to our current shareholders registration rights, as of June 30, 2013, 2,278,185 ordinary shares were outstanding share
options granted under our equity incentive plans and we had outstanding warrants to purchase 9,766 ordinary shares. Following this offering, we intend to file a registration statement on Form S-8 under the U.S. Securities Act of 1933 registering
shares under our equity incentive plans. Shares included in such registration statement will be available for sale in the public
market immediately after such filing, subject to vesting provisions, except for shares held by affiliates who will have certain restrictions on their ability to sell.

You may be subject to adverse United States federal income tax consequences if we are classified as a Controlled Foreign Corporation.

Each Ten Percent Shareholder in a non-U.S. corporation that is classified as a controlled foreign corporation, or
a CFC, for United States federal income tax purposes generally is required to include in income for U.S. federal tax purposes such Ten Percent Shareholders pro rata share of the CFCs Subpart F income and investment of
earnings in U.S. property, even if the CFC has made no distributions to its shareholders. A non-U.S. corporation generally will be classified as a CFC for United States federal income tax purposes if Ten Percent Shareholders own, directly or
indirectly, more than 50% of either the total combined voting power of all classes of stock of such corporation entitled to vote or of the total value of the stock of such corporation. A Ten Percent Shareholder is a United States person
(as defined by the U.S. Internal Revenue Code of 1986, as amended (the Code)) who owns or is considered to own 10% or more of the total combined voting power of all classes of stock entitled to vote of such corporation. The determination
of CFC status is complex and includes attribution rules, the application of which is not entirely certain.

We do not believe
that we were a CFC for the taxable year ended December 31, 2012 or that we are currently a CFC. It is possible, however, that following this offering, a shareholder treated as a United States person for United States federal income tax purposes will
acquire, directly or indirectly, enough shares to be treated as a Ten Percent Shareholder after application of the constructive ownership rules and, together with any other Ten Percent Shareholders of the Company, cause the Company to be treated as
a CFC for United States federal income tax purposes. We believe that immediately following this offering certain of our shareholders are Ten Percent Shareholders for United States federal income tax purposes. Holders should consult their own tax
advisors with respect to the potential adverse U.S. tax consequences of becoming a Ten Percent Shareholder in a CFC.

Our U.S.
shareholders may suffer adverse tax consequences if we are characterized as a passive foreign investment company.

Generally, if for any taxable year 75% or more of our gross income is passive income, or at least 50% of the average quarterly value of
our assets (which, assuming we were not a CFC for the year being tested, would be

measured by fair market value of the assets, and for which purpose the total value of our assets may be determined in part by the market value of our ordinary shares, which is subject to change)
are held for the production of, or produce, passive income, we would be characterized as a passive foreign investment company, or PFIC, for United States federal income tax purposes. Our status as a passive foreign investment company may also depend
on how quickly we utilize the cash proceeds from this offering in our business. Based on our belief that we were not a CFC prior to this offering in the current taxable year and on certain estimates of our gross income and gross assets, our intended
use of proceeds of this offering, and the nature of our business, we do not expect that we will be classified as a PFIC for the taxable year ending December 31, 2013. However, because PFIC status is based on our income, assets and activities
for the entire taxable year, it is not possible to determine whether we will be characterized as a PFIC for the 2013 taxable year until after the close of the year. There can be no assurance that we will not be considered a PFIC for any taxable
year. If we are characterized as a PFIC, our United States shareholders may suffer adverse tax consequences, including having gains realized on the sale of our ordinary shares treated as ordinary income, rather than a capital gain, the loss of the
preferential rate applicable to dividends received on our ordinary shares by individuals who are United States holders, and having interest charges apply to distributions by us and the proceeds of share sales. If we are characterized as a PFIC,
certain elections may be available that would alleviate some of the adverse consequences of PFIC status and result in an alternative treatment (such as mark-to-market treatment) of our ordinary shares; however, we do not intend to provide the
information necessary for U.S. holders to make qualified electing fund elections if we are classified as a PFIC. See Taxation and Government ProgramsUnited States Federal Income TaxationPassive Foreign Investment Company
Considerations.

You will experience immediate and substantial dilution in the net tangible book value of the ordinary shares you
purchase in this offering.

The initial public offering price of our ordinary shares substantially exceeds the net
tangible book value per share of our ordinary shares immediately after this offering. Therefore, if you purchase our ordinary shares in this offering, you will suffer, as
of , 2013, immediate dilution of $ , per share or $
if the underwriters exercise their option in full, in net tangible book value after giving effect to the sale of ordinary shares in this offering at an assumed public offering price of $
per share, the midpoint of the estimated initial public offering price range set forth on the cover page of this prospectus, less underwriting discounts and commissions and the estimated expenses
payable by us. If outstanding options to purchase our ordinary shares are exercised in the future, you will experience additional dilution. See Dilution.

Provisions of Israeli law and our amended and restated articles of association to be effective upon the closing of this offering may delay, prevent or make undesirable an acquisition of all or a
significant portion of our shares or assets.

Provisions of Israeli law and our amended and restated articles of
association to be effective upon the closing of this offering could have the effect of delaying or preventing a change in control and may make it more difficult for a third-party to acquire us or our shareholders to elect different individuals to
our board of directors, even if doing so would be considered to be beneficial by some of our shareholders, and may limit the price that investors may be willing to pay in the future for our ordinary shares. Among other things:



Israeli corporate law regulates mergers and requires that a tender offer be effected when more than a specified percentage of shares in a company are
purchased;



Israeli corporate law does not provide for shareholder action by written consent unless such consent is unanimous, thereby requiring all shareholder
actions to be taken at a general meeting of shareholders;



our articles of association divide our directors into three classes each of which is elected once every three years;



our articles of association do not permit a director to be removed except by a vote of 75% of our shareholders entitled to vote at a general meeting of
shareholders;



our articles of association require that director vacancies may only be filled by our board of directors; and

our articles of association prevent business combinations with interested shareholders for a period of three years after the
date of the transaction in which the person became an interested shareholder, unless the business combination is approved in accordance with our articles of association by a general meeting of our shareholders or satisfies other requirements
specified in our articles of association.

Further, Israeli tax considerations may make potential
transactions undesirable to us or to some of our shareholders whose country of residence does not have a tax treaty with Israel granting tax relief to such shareholders from Israeli tax. With respect to mergers, Israeli tax law allows for tax
deferral in certain circumstances but makes the deferral contingent on the fulfillment of numerous conditions, including a holding period of two years from the date of the transaction during which certain sales and dispositions of shares of the
participating companies are restricted. Moreover, with respect to certain share swap transactions, the tax deferral is limited in time, and when such time expires, the tax becomes payable even if no actual disposition of the shares has occurred. See
Description of Share CapitalAcquisitions under Israeli Law.

We have broad discretion over the use of proceeds we
receive in this offering and may not apply the proceeds in ways that increase the value of your investment.

Our
management will have broad discretion in the application of the net proceeds from this offering and, as a result, you will have to rely upon the judgment of our management with respect to the use of these proceeds. Our management may spend a portion
or all of the net proceeds in ways that not all shareholders approve of or that may not yield a favorable return. The failure by our management to apply these funds effectively could harm our business.

We have not yet determined whether our existing internal controls over financial reporting systems are compliant with Section 404 of the
Sarbanes-Oxley Act, and we cannot provide any assurance that there are no material weaknesses or significant deficiencies in our existing internal controls.

Pursuant to Section 404 of the Sarbanes-Oxley Act and the related rules adopted by the SEC and the Public Company Accounting Oversight Board, starting with the second annual report that we file with
the SEC after the consummation of this offering, our management will be required to report on the effectiveness of our internal control over financial reporting. In addition, once we no longer qualify as an emerging growth company under
the JOBS Act and lose the ability to rely on the exemptions related thereto discussed above, our independent registered public accounting firm will also need to attest to the effectiveness of our internal control over financial reporting under
Section 404. We have not yet commenced the process of determining whether our existing internal controls over financial reporting systems are compliant with Section 404 and whether there are any material weaknesses or significant
deficiencies in our existing internal controls. This process will require the investment of substantial time and resources, including by our Chief Financial Officer and other members of our senior management. In addition, we cannot predict the
outcome of this determination and whether we will need to implement remedial actions in order to implement effective control over financial reporting. The determination and any remedial actions required could result in us incurring additional costs
that we did not anticipate. Irrespective of compliance with Section 404, any failure of our internal controls could have a material adverse effect on our stated results of operations and harm our reputation. As a result, we may experience
higher than anticipated operating expenses, as well as higher independent auditor fees during and after the implementation of these changes. If we are unable to implement any of the required changes to our internal control over financial reporting
effectively or efficiently or are required to do so earlier than anticipated, it could adversely affect our operations, financial reporting and/or results of operations and could result in an adverse opinion on internal controls from our independent
auditors.

Risks Relating to Our Incorporation and Location in Israel

Conditions in Israel could adversely affect our business.

We are
incorporated under Israeli law and our principal executive offices are located in Israel. Accordingly, political, economic and military conditions in Israel directly affect our business. Since the State of Israel was

established in 1948, a number of armed conflicts have occurred between Israel and its Arab neighbors. Although Israel has entered into various agreements with Egypt, Jordan and the Palestinian
Authority, there has been an increase in unrest and terrorist activity, which began in September 2000 and has continued with varying levels of severity into 2013. In mid-2006, Israel was engaged in an armed conflict with Hezbollah in Lebanon,
resulting in thousands of rockets being fired from Lebanon and disrupting most day-to-day civilian activity in northern Israel. Starting in December 2008, for approximately three weeks, Israel engaged in an armed conflict with Hamas in the Gaza
Strip, which involved missile strikes against civilian targets in various parts of Israel and negatively affected business conditions in Israel. In 2012 once again Israel engaged in an armed conflict with Hamas in the Gaza Strip, with missiles
reaching as far as Tel-Aviv. Popular uprisings in various countries in the Middle East and North Africa are affecting the political stability of those countries. Such instability may lead to deterioration in the political and trade relationships
that exist between the State of Israel and these countries. Any armed conflicts, terrorist activities or political instability in the region could adversely affect our business, financial condition and results of operations. Our commercial insurance
does not cover losses that may occur as a result of events associated with the security situation in the Middle East, such as damages to our facilities resulting in disruption of our operations. Although the Israeli government currently covers the
reinstatement value of direct damages that are caused by terrorist attacks or acts of war, we cannot assure you that this government coverage will be maintained or will be adequate in the event we submit a claim.

A number of countries, principally in the Middle East, still restrict doing business with Israel and Israeli companies, and additional
countries may impose restrictions on doing business with Israel and Israeli companies if hostilities in Israel or political instability in the region continue or increase. These restrictions may limit materially our ability to distribute our
products to users in these countries or establish distributor relationships with companies operating in these regions. Any hostilities involving Israel or the interruption or curtailment of trade between Israel and its present trading partners, or
significant downturn in the economic or financial condition of Israel, could adversely affect our operations, cause our revenues to decrease and adversely affect the share price of publicly traded companies having operations in Israel, such as us.
Similarly, Israeli corporations are limited in conducting business with entities from several countries. For example, in 2008 the Israeli legislature adopted a law forbidding any investments in entities that transact business with Iran. Moreover,
individuals in certain geographical regions may refrain from doing business with Israel and Israeli companies as a result of their objection to Israeli foreign or domestic policies.

Our operations may be disrupted by the obligations of personnel to perform military service.

As of June 30, 2013, we had 346 employees based in Israel. Our employees in Israel, including executive officers, may be called upon to perform up to 56 days per each three year period, (in some cases
more, e.g. officers may be called to serve up to 84 days per each three year period) of military reserve duty until they reach the age of 40 (and in some cases, depending on their certain military profession up to 45 or even 49) and, in
emergency circumstances, could be called to immediate and unlimited active duty (however, this would need to be approved by the Israeli government). In response to increased tension and hostilities, there have been since September 2000 occasional
call-ups of military reservists, including in connection with the mid-2006 war in Lebanon, the December 2008 conflict with Hamas and the 2012 conflict in the Gaza Strip, and it is possible that there will be additional call-ups in the future. Our
operations could be disrupted by the absence of a significant number of employees related to military service or the absence for extended periods of one or more of our key employees for military service. Such disruptions in the future could
materially adversely affect our business and results of operations, especially if we are unable to replace these key employees with other personnel qualified in information technology and data optimization.

The tax benefits that are available to us require us to continue to meet various conditions and may be terminated or reduced in the future, which
could increase our costs and taxes.

We are eligible for certain tax benefits provided to Beneficiary
Enterprises under the Israeli Law for the Encouragement of Capital Investments, 1959, referred to as the Investment Law. In order to remain eligible for the tax benefits for Beneficiary Enterprises we must continue to meet certain
conditions stipulated in the

Investment Law and its regulations, as amended. In addition, In September 2011, we received a tax ruling from the Israeli Tax Authorities, according to which, among other things, the Israeli Tax
Authorities approved the following: (i) our status as an Industrial Enterprise; and (ii) that the expansion of our enterprise is considered as a Beneficiary Enterprise with 2009 as an elected year of operations, all
under the Investment Law as amended by 2005 Amendment. The benefits available to us under this tax ruling are subject to the fulfillment of conditions stipulated in the ruling. If we do not meet these conditions, the ruling may be abolished which
would result in adverse tax consequences to us. Further, in the future these tax benefits may be reduced or discontinued. If these tax benefits are reduced, cancelled or discontinued, our Israeli taxable income would be subject to regular Israeli
corporate tax rates. The standard corporate tax rate for Israeli companies in 2010 was 25% of their taxable income and was reduced to 24% in 2011. The corporate tax rate was increased to 25% in 2012 and to 26.5% for 2014 and thereafter.
Additionally, if we increase our activities outside of Israel through acquisitions, for example, our expanded activities might not be eligible for inclusion in future Israeli tax benefit programs. See Taxation and Government
ProgramsIsraeli Tax Considerations and Government ProgramsLaw for the Encouragement of Capital Investments, 5719-1959.

It may be difficult to enforce a U.S. judgment against us, our officers and directors and the Israeli experts named in this prospectus in Israel or
the United States, or to assert U.S. securities laws claims in Israel or serve process on our officers and directors and these experts.

We are incorporated in Israel. Only some of our directors and none of our executive officers are resident in the United States. Our independent registered public accounting firm is not a resident of the
United States. Most of our assets and the assets of these persons are located outside the United States. Therefore, it may be difficult for an investor, or any other person or entity, to enforce a U.S. court judgment based upon the civil liability
provisions of the U.S. federal securities laws against us or any of these persons in a U.S. or Israeli court, or to effect service of process upon these persons in the United States. Additionally, it may be difficult for an investor, or any other
person or entity, to assert a claim based on U.S. securities laws in original actions instituted in Israel. Israeli courts may refuse to hear a claim based on a violation of U.S. securities laws on the grounds that Israel is not the most appropriate
forum in which to bring such a claim. Even if an Israeli court agrees to hear a claim, it may determine that Israeli law and not U.S. law is applicable to the claim. If U.S. law is found to be applicable, the content of applicable U.S. law must be
proved as a fact which can be a time-consuming and costly process. Certain matters of procedure will also be governed by Israeli law. There is little binding case law in Israel addressing the matters described above. See Enforceability of
Civil Liabilities.

Your rights and responsibilities as our shareholder will be governed by Israeli law which may differ in some
respects from the rights and responsibilities of shareholders of U.S. corporations.

Since we are incorporated under
Israeli law, the rights and responsibilities of our shareholders are governed by our articles of association and Israeli law. These rights and responsibilities differ in some respects from the rights and responsibilities of shareholders in United
States-based corporations. In particular, a shareholder of an Israeli company has a duty to act in good faith and in a customary manner in exercising its rights and performing its obligations towards the company and other shareholders and to refrain
from abusing its power in the company, including, among other things, in voting at the general meeting of shareholders on certain matters, such as an amendment to the companys articles of association, an increase of the companys
authorized share capital, a merger of the company and approval of related party transactions that require shareholder approval. A shareholder also has a general duty to refrain from discriminating against other shareholders. In addition, a
controlling shareholder or a shareholder who knows that it possesses the power to determine the outcome of a shareholders vote or to appoint or prevent the appointment of an office holder in the company or has another power with respect to the
company, has a duty to act in fairness towards the company. However, Israeli law does not define the substance of this duty of fairness. See ManagementApproval of Related Party Transactions under Israeli LawFiduciary Duties of
Directors and Executive Officers. Because Israeli corporate law underwent extensive revisions approximately fifteen years ago, some of the parameters and implications of the provisions that govern shareholder behavior have not been clearly
determined. These provisions may be

interpreted to impose additional obligations and liabilities on our shareholders that are not typically imposed on shareholders of United States corporations.

Additionally, we expect the quorum requirements for meetings of our shareholders to be lower than is customary for domestic issuers. As
permitted under the Companies Law, pursuant to our amended and restated articles of association to be effective upon the closing of this offering, the quorum required for an ordinary meeting of shareholders will consist of at least two shareholders
present in person, by proxy or by other voting instrument in accordance with the Companies Law, who hold at least 25% of the voting power of our shares (and in an adjourned meeting, with some exceptions, any number of shareholders). For an adjourned
meeting at which a quorum is not present, the meeting may generally proceed irrespective of the number of shareholders present at the end of half an hour following the time fixed for the meeting.

We make forward-looking statements in this prospectus that are subject to risks and uncertainties. These forward-looking
statements include information about possible or assumed future results of our business, financial condition, results of operations, liquidity, plans and objectives. In some cases, you can identify forward-looking statements by terminology such as
believe, may, estimate, continue, anticipate, intend, should, plan, expect, predict, potential, or the negative of
these terms or other similar expressions. The statements we make regarding the following matters are forward-looking by their nature:



our expectations regarding future changes in our cost of revenues and our operating expenses on an absolute basis and as a percentage of our revenues;



our expectation that the percentage of revenues we derive from outside of North America will increase in the future;



our planned level of capital expenditures and our belief that our existing cash and cash from operations will be sufficient to fund our operations for
at least the next twelve months; and



our plans to make our product, support and communication channels available in additional languages and to expand our payment infrastructure to
transact in additional local currencies and accept additional payment methods.

The preceding list is not
intended to be an exhaustive list of all of our forward-looking statements. The forward-looking statements are based on our beliefs, assumptions and expectations of future performance, taking into account the information currently available to us.
These statements are only predictions based upon our current expectations and projections about future events. There are important factors that could cause our actual results, levels of activity, performance or achievements to differ materially from
the results, levels of activity, performance or achievements expressed or implied by the forward-looking statements. In particular, you should consider the risks provided under Risk Factors in this prospectus.

You should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected
in the forward-looking statements are reasonable, we cannot guarantee that future results, levels of activity, performance and events and circumstances reflected in the forward-looking statements will be achieved or will occur. Except as required by
law, we undertake no obligation to update publicly any forward-looking statements for any reason after the date of this prospectus, to conform these statements to actual results or to changes in our expectations.

We estimate that the net proceeds to us from this offering, after deducting underwriting discounts and estimated offering expenses, will
be approximately $ million (or approximately $ million if the underwriters exercise their option in full), assuming the shares are offered at $
per share, which is the midpoint of the estimated offering price range set forth on the cover page of this prospectus.

A $1.00 increase (decrease) in the assumed initial public offering price of $ per share would increase (decrease) the net proceeds to us from this offering
by approximately $ million, assuming the number of shares offered by us as set forth on the cover page of this prospectus remains the same and after deducting the underwriting discounts and
commissions. Similarly, each increase (decrease) of 100,000 shares in the number of ordinary shares offered by us would increase (decrease) the net proceeds to us from this offering by approximately $
million, assuming that the assumed initial public offering price remains the same, and after deducting the underwriting discounts and commissions.

The principal purposes of this offering are to obtain additional working capital, to create a public market for our ordinary shares and to facilitate our future access to the public equity markets. We
intend to use the net proceeds from this offering for general corporate purposes focused on growing our business. We expect to use a significant portion to hire additional personnel for our research and development and support and call center
functions, and to increase our selling and marketing expenses focused on user acquisition. We may also use a portion of the net proceeds to make acquisitions or investments in complementary companies or technologies, although we do not have any
agreement or understanding with respect to any such acquisition or investment at this time. However, we do not currently have specific plans or commitments with respect to the net proceeds from this offering and, accordingly, are unable to quantify
the allocation of such proceeds among the various potential uses. We will have broad discretion in the way that we use the net proceeds of this offering.

We will not receive any of the proceeds from the sale of ordinary shares by the selling shareholders.

We have never declared or paid any dividends on our ordinary shares. We do not anticipate paying any dividends in the foreseeable future.
We currently intend to retain future earnings, if any, to finance operations and expand our business. Our board of directors has sole discretion whether to pay dividends. If our board of directors decides to pay dividends, the form, frequency and
amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that our directors may deem relevant.

The following table sets forth our cash and cash equivalents and total capitalization as of June 30, 2013, as follows:



on an actual basis;



on a pro forma basis to reflect the automatic conversion of all outstanding preferred shares into ordinary shares upon the closing of this offering;



on a pro forma as adjusted basis to give effect to the conversion described in the preceding clause and to reflect the issuance and sale of ordinary
shares in this offering at an assumed initial public offering price of $ per ordinary share, the midpoint of the initial public offering price range set forth on the cover page of this prospectus,
after deducting underwriting discounts and commissions and the estimated offering expenses payable by us.

You should read this information in conjunction with our consolidated financial statements and the related notes appearing at the end of
this prospectus and the Managements Discussion and Analysis of Financial Condition and Results of Operations section and other financial information contained in this prospectus.

A $1.00 increase (decrease) in the assumed initial public offering price of
$ per ordinary share, would increase (decrease) the as adjusted amount of each of cash and cash equivalents, additional paid-in capital, total equity and total capitalization by approximately
$ million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting underwriting discounts and commissions and estimated
offering expenses payable by us.

If you invest in our ordinary shares in this offering, your ownership interest will be immediately diluted to the extent of the difference
between the initial public offering price per share and the pro forma as adjusted net tangible book value per ordinary share after this offering. Our net tangible book value as of June 30, 2013 was
$ per ordinary share.

After giving effect to the automatic conversion of all
outstanding preferred shares upon the closing of this offering and the sale of ordinary shares that we are offering at an assumed initial public offering price of $ per share, after deducting
underwriting discounts and commissions and estimated offering expenses payable by us, our net tangible book value on an adjusted basis as of June 30, 2013 would have been $ per ordinary share.
This amount represents an immediate decrease in net tangible book value of $ per ordinary share to our existing shareholders and an immediate increase in net tangible book value of
$ per ordinary share to new investors purchasing ordinary shares in this offering. We determine dilution by subtracting the pro forma as adjusted net tangible book value per share after this offering
from the amount of cash that a new investor paid for an ordinary share.

The following table illustrates this dilution:

A $1.00 increase (decrease) in the assumed initial public offering price of $
per ordinary share would increase (decrease) the pro forma as adjusted amount of each of cash, cash equivalents and short-term investments, share capital, share premium, additional paid-in capital,
total equity and total capitalization by approximately $ million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after
deducting underwriting discounts and commissions and estimated offering expenses payable by us.

If the underwriters exercise
their option to purchase additional ordinary shares in full in this offering, the pro forma as adjusted net tangible book value after the offering would be $ per share, the decrease in net tangible
book value per share to existing shareholders would be $ and the increase in net tangible book value per share to new investors would be $ per share, in
each case assuming an initial public offering price of $ per ordinary share.

The following table summarizes, as of
, 2013, the differences between the number of shares purchased from us, the total consideration paid to us in cash and the
average price per share that existing shareholders paid during the past five years, on the one hand, and new investors are paying in this offering, on the other hand. The calculation below is based on an assumed initial public offering price of $
per share before deducting underwriting discounts and commissions and estimated offering expenses payable by us.

The foregoing tables and calculations exclude (1) 2,373,640 ordinary shares reserved for issuance
under our equity incentive plans as of June 30, 2013 of which options to purchase 2,278,185 shares had been granted at a weighted average exercise price of $2.36 per share, and (2) warrants to purchase 9,766 ordinary shares with an
exercise price of $20.48 per share.

To the extent any of these outstanding options is exercised, there will be further dilution
to new investors. To the extent all of such outstanding options had been exercised as of June 30, 2013, the pro forma as adjusted net tangible book value per share after this offering would be $ ,
and total dilution per share to new investors would be $ .

If the underwriters
exercise their option to purchase additional shares in full:



the percentage of ordinary shares held by existing shareholders will decrease to approximately % of the
total number of our ordinary shares outstanding after this offering; and



the number of shares held by new investors will increase
to , or approximately % of the total number of our ordinary shares outstanding
after this offering.

The following tables set forth our selected consolidated financial and other data. You should read the following selected consolidated

Overview

We are a leading global web development platform with one of the largest number of registered users in the world. We empower more than
37 million registered users in 190 countries to create and manage a fully integrated and dynamic digital presence. We are pioneering a new approach to web development and management that provides an easy-to-use yet powerful cloud-based platform
that eliminates complex coding and expensive design services. Our solutions enable millions of businesses, organizations, professionals and individuals to take their businesses, brands and workflow online without the need to engage expensive
development and design firms or other costly professionals.

We were founded in late 2006 and have achieved a number of
significant milestones since then:



In April 2008, we launched our Wix Editor, which enabled the creation of a digital presence in Flash format.



In October 2008, we launched our premium subscription offering and by July 2009 gained our first one million users and 20,495 premium subscriptions.



By June 2011, we reached 10 million users and by January 2012, we supported five languages across 190 countries.



In March 2012, we released our advanced HTML5 Editor, which greatly improved our service offering and support for mobile devices, allowed our users
greater functionality and customization and expanded our abilities to develop new solutions to offer our users. By April 2012, we reached 20 million registered users.



In October 2012, we introduced the Wix App Market with Wix and third-party developed applications, or apps, providing users with additional workflow
functionality which can be integrated into their websites.



Throughout 2013, we continued to grow at a rapid pace and as of August 31, 2013, we had more than 37 million registered users and 679,536 premium
subscriptions and averaged 19,762 app installations per day during the month of August.

We have experienced
significant growth in our user base and premium subscriptions in recent periods. Our users grew from 6.5 million at December 31, 2010 to 28.2 million at December 31, 2012, representing a 108% compounded annual growth rate. Our
premium subscriptions have grown from 149,084 to 469,589 over the same period, representing a 78% compounded annual growth rate. Through June 30, 2013, we had achieved 14 consecutive quarters of sequential growth in the accumulated number of premium
subscriptions. We have also achieved 14 consecutive quarters of growth in revenues and collections. We had revenues of $9.9 million, $24.6 million and $43.7 million and collections of $13.8 million, $29.6 million and
$52.5 million in 2010, 2011 and 2012, respectively. We had a net loss of $11.5 million, $22.7 million and $15.0 million in 2010, 2011 and 2012, respectively. We had revenues of $34.1 million, collections of $41.9 million and a net loss of $10.1
million during the six months ended June 30, 2013.

We derive the substantial majority of our revenue from monthly and annual premium subscriptions for our solutions. Annual subscriptions
provide benefits to our operating model because we are able to collect cash up front, increase overall retention rates and have greater visibility into revenues. As a result, we provide incentives to drive annual subscriptions, including a lower
average monthly price relative to a monthly subscription. We have noticed, however, that promotions that further lower the effective price of an annual subscription can result in attracting users who do not renew their subscription once the
promotion is no longer available. We therefore seek to strike a balance between attracting annual subscriptions and maintaining a user base that is loyal to our offering. As of August 31, 2013, 64% of our overall premium subscriptions were annual
and 36% were monthly.

In addition, we generate revenues from selling third-party domain registration, revenue from
Wix-developed apps and revenues from sharing agreements with third-party developers for apps sold through our App Market. We launched our App Market in the last quarter of 2012 and therefore generated negligible revenues from it in 2012.

Our solutions are offered through a freemium model in which users can register with an e-mail address and build, launch and manage a
digital presence for free for an unlimited amount of time. A premium subscription, which provides users with additional solutions such as extra bandwidth and storage, Wix ad removal, access to Google Analytics, domain connectivity and eCommerce
solutions, can be purchased at any time. Because we increase our pipeline of potential premium subscriptions by acquiring more registered users and over half of the new premium subscriptions in a typical month in recent periods were generated by
registered users who registered in previous months, we are focused on building a large user base. The number of new registered users we attract is therefore a key factor in growing our premium subscription base, which drives our revenues and
collections. Users that purchase premium subscriptions often decide to do so several months, quarters or years after initially registering with us. Thus, in each period, new premium subscriptions include users who registered in that period as well
as users who initially registered with us in previous periods. We believe this characteristic of our business model provides us with a growing pipeline of potential subscriptions as our user base grows.

User Acquisition Spending

Approximately 59% of the premium subscriptions generated by users that registered in August 2013 came from organic and direct sources, meaning visitors that reached us via unpaid search results or by
typing the URL of our website in their browser. Our selling and marketing spending to attract additional new registered users focuses primarily on online advertising. The types of paid marketing channels that we target are cost-per-click
advertisements on search engines and social networking sites and targeted and generic banner advertisements on other sites.

Our
registered user acquisition strategy is based on the significant amounts of data that we have accumulated regarding the behavior of registered users that we acquire from different sources. We extrapolate from this historical user behavior data to
predict future user behavior and make decisions regarding our marketing expenditures. In order to grow our registered user base and in turn our premium subscriptions, we consider the time period over which we seek to return an amount of
collections equal to the marketing expenditures used to attract a specific group of registered users during a particular period, which we refer to as a cohort. In order to achieve the targeted time for return on those marketing
expenditures, we adjust the paid marketing channels that we use and the amounts that we pay to acquire new registered users in addition to considering those registered users that come from organic and direct sources. For example, we could pay a
substantially identical amount to acquire fewer users that generate premium subscriptions at a higher rate versus acquiring more users that generate premium subscriptions at a lower rate. The net amount of premium subscriptions would be the
same, but in the former case we would have acquired fewer new registered users overall. We prefer the latter case due to the benefit of gaining more registered users and having a larger pipeline of registered users that can generate premium
subscriptions over time based on the long tail of premium subscriptions that each cohort generates. This larger number of users also creates more overall users of our platform who can recommend others to our site. In addition, a
single registered user can purchase multiple

premium subscriptions. This fact, coupled with our preference to grow the size of our user base even if the rate of purchase of premium subscriptions is lower, is why we do not consider the rate
at which registered users purchase a premium subscription (or any other measure of conversion) to be a meaningful measure of the success of our business.

Since we target our marketing expenditures by extrapolating from historical user behavior to predict future user behavior, an event that disrupts that behavior can adversely impact the returns that we
projected for a particular cohort. For example, an event such as a change to or a bug in a browser that affects all websites viewed on that browser, including websites created using our platform, can adversely impact user behavior and in turn our
projected returns. Moreover, significant announcements by third parties can also have the same effect. For example, an announcement by Adobe to stop supporting Flash on mobile devices when our platform was Flash-based only, in the past caused us to
attract less new registered users than we projected during the short-term impact of such announcement.

Premium
Subscription Origination Analysis

To track our growth, progress and execution of marketing efforts, including
achievement of our targeted time for return on marketing expenditures, we regularly review the relationship between origination of our users and origination of premium subscriptions.

First Quarter 2010 User Cohort. The following chart summarizes the number of premium subscriptions that originated during each
quarterly period from the first quarter of 2010 to the first quarter of 2013 from the 919,221 registered users that first registered with us in the first quarter of 2010. We refer to this group of users as our first quarter 2010 User Cohort. The
first quarter 2010 User Cohort is representative of trends we have seen in premium subscription originations, and we believe it is consistent with our users subscription purchasing behavior in recent periods.

Through June 30, 2013, the first quarter 2010 User Cohort generated a total of 64,493 new premium subscriptions and continued to generate
premium subscriptions up through and during the third quarter of 2013. As of the end of its first quarter, there were 18,562 premium subscriptions that had been purchased by users from the first quarter 2010 User Cohort. Fourteen quarters later
there were still 19,472 premium subscriptions from users that originated from this same cohort. We spent approximately $1.1 million in advertising expenses to acquire this user cohort. Since originating, premium subscriptions from users in this
cohort have resulted in aggregate revenues recognized of $7.8 million and $9.0 million in collections through the second quarter of 2013. Approximately $1.2 million of deferred revenue relating to purchases by this user cohort remained outstanding
at June 30, 2013. Furthermore, this cohort continues to generate revenue and collections beyond that date.

Second Quarter 2013 Premium Subscription Cohort. The following chart summarizes the
composition of premium subscriptions purchased in the second quarter of 2013 by user registration date. In the second quarter of 2013, we sold 154,171 premium subscriptions, of which 65,857 premium subscriptions, or 43% of the total, were purchased
by users that first registered with us in the same quarter. The remaining 57% of premium subscriptions purchased in the second quarter of 2013 were by users who initially registered in earlier quarters.

Premium Subscriptions in First Quarter 2013 by User Registration Date

Some users account for multiple premium subscriptions. For example, users who are professional web
designers often use our platform to support their business, building and designing sites for their own customers. We believe these trends illustrate the increasing value of our user base as we continue to increase the number of our users.

Key Financial and Operating Metrics

We monitor the following key operating and financial metrics to evaluate the growth of our business, measure the effectiveness of our marketing efforts, identify trends affecting our business, formulate
financial projections and make strategic decisions:



Collections. We define collections as total cash collected by us from our customers in a given period. Collections is calculated by adding the
change in deferred revenues for a particular period to revenues for the same period. Collections consists primarily of amounts from annual and monthly premium subscriptions by users, which are deferred and recognized as revenues over the terms of
the subscriptions and payments by our users for domains, which are also recognized ratably over the term of the service period. We believe that collections is a leading indicator of the growth of our overall business. Collections is non-GAAP
financial measure. For a reconciliation of collections to the most directly comparable U.S. GAAP measure, see SummarySummary Consolidated Financial and Other DataNon-GAAP Financial MeasuresCollections.



Free cash flow. We define free cash flow as cash flow from operating activities minus capital expenditures. We believe that free cash flow is
useful in evaluating our business because free cash flow reflects the cash surplus available or used to fund the expansion of our business after the payment of capital expenditures relating to the necessary components of ongoing operations. Free
cash flow is currently negative because of the substantial investments that we are making in expanding our business. Free cash flow is a non-GAAP financial measure. For reconciliation of free cash flow to the

Number of registered users at period end.We define this metric as the total number of users, including those who have purchased
premium subscriptions, who are registered with Wix.com with a unique e-mail address at the end of the period. The length of time that users take following registration to design and publish a website varies significantly from hours to years, and
many users never publish a website. We have no means of assessing the level of engagement of a particular user following registration or how close a user is to potentially publishing their website. We view the number of users at the end of a given
period as a key indicator of the attractiveness and usability of our product, as well as the strength of our pipeline that can generate premium subscriptions over time. We believe that growth in premium subscriptions will be driven significantly by
our ability to add users to our platform and to further enhance our product and service offerings.



Number of premium subscriptions at period end. We define this metric as the total monthly and annual premium subscriptions as of
the end of the period. A single user can purchase multiple premium subscriptions. Because we derive the majority of our revenues and collections from premium subscriptions, we believe that this is a key metric in understanding our growth. The total
number of premium subscriptions is also impacted by the renewal rates of our existing premium subscriptions. Premium subscriptions terminate due to an active decision by a user not to renew their subscription or due to the failure of a user to
update his or her credit card information upon expiration or termination. Our renewal rates demonstrate our strong value proposition to our premium subscriptions. We observe the average renewal rates of the cohorts of our users with premium
subscriptions to measure the effectiveness of our platform and satisfaction of our users. From January 1, 2010 to June 30, 2013, an average of 71% of our registered users with annual subscriptions renewed their subscriptions after the first year.
Over the same period, an average of 51% of our registered users with monthly subscriptions maintained their subscriptions after one year. Renewal rates improved in the second and third years of subscription for both annual and monthly subscriptions.
Registered users with annual subscriptions who had renewed in the first year, renewed at a rate of 71% in the second year, while those with monthly subscriptions renewed at a rate of 65% in the second year. Registered users with annual subscriptions
who had renewed for two years, renewed at a rate of 72% in the third year, while those with monthly subscriptions renewed at a rate of 68% in the third year.

Components of Statements of Operations

Revenues

Sources of Revenues. We derive the substantial majority of our revenues from monthly and annual premium subscriptions by
businesses, organizations, professionals and individuals to our various premium subscriptions, which include extra bandwidth and storage, Wix ad removal, access to Google Analytics, domain connectivity and eCommerce solutions.

We derive a small portion of our revenues from selling third-party domain registration. Revenues from domain name registrations accounted
for approximately 5% of revenues in 2012 and 6% of revenues in the six months ended June 30, 2013. We also derive a small portion of our revenues from our App Market consisting of revenues derived from sharing agreements with third parties pursuant
to which we receive a portion of the collected revenues of any app to which our users subscribe. Revenues from app installations from our App Market accounted for a negligible amount of revenues in 2012 and the six months ended June 30, 2013. We
plan to increase the number of value-added services that we offer and the associated revenues we derive from these services.

Payment and Revenue Recognition. Revenues from premium subscriptions, domain name registration and apps developed by us are
recognized ratably over the term of the service period. We offer new premium subscription packages for a 14-day trial period during which the user can cancel the subscription at any time and receive a full refund. We classify such amounts collected
from new subscriptions as customer deposits until the

end of the 14-day trial period. After the 14-day trial period has ended, we recognize premium subscription revenues ratably over the term of the service period, either monthly or annually. We do
not offer trial periods for domain name registrations. Substantially all deferred revenues consist of amounts received from premium subscriptions and domain registration sales that are not yet recognized as revenues. For revenues from apps developed
by third-party app developers, we account on a net basis by recognizing only the commission we retain from each sale. We do not reflect in our financial statements the portion of the gross amount billed to users with apps that we remit to
third-party app developers. See Application of Critical Accounting Policies and EstimatesRevenue Recognition.

We bill our premium subscriptions in advance through our users credit or debit cards and a small amount through PayPal. We currently use third-party billing systems integrated into our website, and
an internal billing system, both which provide a portal for users to submit credit or debit card information for processing. Payment occurs after the credit card information entered for the transaction passes through the validation and verification
process of our internal and third-party billing providers and processors.

We expect the percentage of revenues derived from outside of North America to increase over time as we
continue to further penetrate internationally. Additional international adoption of our solutions and services is driven by our ability to offer our platform in local languages and offer local billing solutions. When penetrating new markets, we
first focus on establishing an operational online billing system, if needed, prior to launching and investing in local marketing activities. We currently offer our platform in five languagesEnglish, French, Spanish, Portuguese and Italian, and
we have plans to add more languages. We have historically launched our platform in new markets without the need for local support staff.

Costs and Expenses

Cost of Revenues. Cost of revenues
consists primarily of costs directly associated with the provision of services, namely, bandwidth and hosting costs for our platform, customer support software solutions and related call center costs along with domain name registration costs. Cost
of revenues also consists of personnel and the related overhead costs, including share-based compensation. We expect cost of revenues to increase with the increase in the number of users but to slightly decrease as a percentage of revenues.

Research and Development. Research and development expenses consist primarily of personnel and the related overhead
costs, including share-based compensation, related to our solutions and service development activities including new initiatives, quality assurance and other related development activities. We expect research and development costs and expenses to
continue to increase on an absolute basis, but to decrease as a percentage of revenues, as we develop new solutions and add functionalities to our existing solutions and services and expand our mobile app offering.

Selling and Marketing. Our primary operating expense is selling and marketing. The significant majority of our selling and
marketing expenses are user acquisition costs, which consist primarily of fees paid to third parties for our cost-per-click advertising, social networking and marketing campaigns and other media advertisements. We intend to continue expanding our
user acquisition efforts to drive revenue growth while focusing on our return-on-

investment targets. Other selling and marketing expenses also consist primarily of personnel and the related overhead costs, including share-based compensation for personnel engaged in marketing,
advertising and promotional activities. Our marketing expenses also include billing costs in connection with the processing fee of our collections. We expect our expenses to increase on an absolute basis as we penetrate our existing markets and
expand to new markets, hire additional personnel and increase our business and collections.

General and Administrative.
General and administrative expenses primarily consist of personnel and overhead related costs, including share-based compensation, for our executive, finance, human resources and administrative personnel. General and administrative expenses also
include legal, accounting and other professional service fees and other corporate expenses. We expect our general and administrative expenses to increase on an absolute basis, but decrease as a percentage of revenues, as we penetrate our existing
markets and expand to new markets, hire additional personnel and incur additional costs related to the growth of our business. We will also incur costs associated with being a public company in the United States, including compliance under the
Sarbanes-Oxley Act of 2002 and rules promulgated by the SEC and the New York Stock Exchange, and director and officer liability insurance.

Financial Income (Expenses), Net. Financial income (expenses), net consists primarily of costs related to derivative instruments we enter into for foreign exchange transactions to hedge a portion
of our payments in NIS, as well as income and expenses related to the change in the fair value of such derivative instruments. In addition, financial income (expenses), net includes the fluctuation in value due to foreign exchange differences
between our monetary assets and liabilities denominated in NIS. We do not have any indebtedness for borrowed amounts.

Other
Expenses. During 2011, we relocated to our current corporate headquarters in Tel Aviv. This relocation resulted in us incurring a capital loss due to the disposal of leasehold improvements and fixed assets. Therefore, we recorded a capital loss
of $0.1 million in 2011 while we recorded no capital gains or losses in 2010 and a minimal amount in 2012 and the six months ended June 30, 2013.

Taxes on Income. As of June 30, 2013, we had not yet generated taxable income in Israel. At the end of our last fiscal year, our net operating loss carry forwards for Israeli tax purposes
amounted to approximately $36.2 million. After we utilize our net operating loss carry forwards, we are eligible for certain tax benefits in Israel under the Law for the Encouragement of Capital Investments, 1959, or the Investment Law.
Accordingly, if we generate taxable income in Israel during the benefit period, we expect our effective tax rate will be lower than the standard corporate tax rate for Israeli companies, which was 25% in 2010, 24% in 2011 and 25% in 2012 and 2013.
The standard corporate tax rate is set to increase to 26.5% in 2014. Our benefit period currently ends in 2020. Our taxable income generated outside of Israel or derived from other sources in Israel which is not eligible for tax benefits will be
subject to the regular corporate tax rate. For more information about the tax benefits available to us as a Beneficiary Enterprise, see Taxation and Government Programs.

Revenues. Revenues increased by $15.2 million, or 80.4%, from $18.9 million in
the six months ended June 30, 2012 to $34.1 million in the six months ended June 30, 2013. The substantial majority of this increase was driven by 65.8% growth in the number of premium subscriptions from 377,945 as of June 30, 2012 to 626,733
as of June 30, 2013. The number of premium subscriptions was favorably impacted by the introduction of versions of our HTML5 product in languages other than English in July 2012, and the introduction of our eCommerce platform for HTML5 in August
2012. Premium subscriptions were also impacted favorably in the six months ended June 30, 2013 by an increase in marketing spend, particularly on social media platforms.

Collections increased by $19.6 million, or 87.9%, from $22.3 million in the six months ended
June 30, 2012 to $41.9 million in the six months ended June 30, 2013. This increase was due to an increase in premium subscriptions from 377,945 to 626,733 as well as domain name registration to a lesser extent.

Costs and Expenses

Cost of Revenues. Cost of revenues increased by $2.5 million, or 64.1%, from $3.9 million in the six months ended June 30, 2012 to $6.4 million in the six months ended June 30, 2013. This increase
was primarily attributable to an increase of $1.1 million in payroll expenses due to increased headcount from 91 to 130, an increase of $0.7 million in domain name costs, an increase of $0.6 million in bandwidth and hosting costs, and an increase of
$0.1 million related to allocated overhead expenses and other costs due to expanded activities.

Research and
Development. Research and development expenses increased by $3.6 million, or 45.6%, from $7.9 million in the six months ended June 30, 2012 to $11.5 million in the six months ended June 30, 2013. This increase was attributable to an increase of
$2.4 million in payroll and consultant fees due to increased headcount from 131 to 202 to support our development plans, an increase of $0.5 million related to allocated overhead expenses, an increase of $0.5 million in other development costs due
to expanded activities, and an increase of $0.2 million in share-based compensation costs.

Selling and Marketing.
Selling and marketing expenses increased by $9.6 million, or 73.8%, from $13.0 million in the six months ended June 30, 2012 to $22.6 million in the six months ended June 30, 2013. This increase was attributable to an increase of $7.8 million
in user acquisition costs and other marketing activities from $10.0 million in the six months ended June 30, 2012 to $17.8 million in the six months ended June 30, 2013 due to the expansion of distribution channels for our products and
services, especially via social networking platforms. It also resulted from an increase of $0.8 million in processing costs of our collections, an increase of $0.7 million in payroll expenses due to increased headcount from 53 to 66, andan increase of $0.3 million in related allocated overhead expenses.

General and Administrative. General and
administrative expenses increased by $1.4 million, or 82.4%, from $1.7 million in the six months ended June 30, 2012 to $3.1 million in the six months ended June 30, 2013. This increase was primarily attributable to an increase of $0.7 million in
legal, audit and other consulting services costs primarily associated with the increase in our operations and our preparation to become a public company, an increase of $0.6 million in payroll expenses due to increased headcount from 19 to 27, which
included an increase of $0.3 million in share-based compensation expenses and an increase of $0.1 million related to allocated overhead expenses and other costs.

Financial Expenses (Income), Net. Financial expenses (income), net decreased by $0.07 million from financial expenses of $0.11 million in the six months ended June 30, 2012 to financial
expenses of $0.04 million in the six months ended June 30, 2013. Financial expenses in the six months ended June 30, 2013 was primarily due to $0.3 million in share-based compensation costs related
to warrants granted in connection with our revolving credit facility, which was offset with a gain of $0.4 million due to foreign exchange fluctuations of the NIS against the U.S. dollar, losses from hedging transactions of $0.1 million and
interest expenses of $0.1 million.

Taxes on Income. Taxes on income increased by $0.5 million from
$0.1 million in the six months ended June 30, 2012 to $0.6 million in the six months ended June 30, 2013. This increase was attributable to an increase of $0.2 million in taxes in the United States and an increase of $0.3 million in
taxes in Brazil.

Year Ended December 31, 2012 Compared to Year Ended December 31, 2011

Revenues. Revenues increased by $19.1 million, or 77.6%, from $24.6 million in 2011 to $43.7 million in 2012. The
substantial majority of this increase in revenues was driven by 56% growth in the number of premium subscriptions from 298,143 as of December 31, 2011 to 469,589 as of December 31, 2012 with virtually no impact from changes in pricing. The
number of premium subscriptions was favorably impacted by the

introduction of our HTML5 platform in March 2012, the introduction of versions of our HTML5 platform in languages other than English in July 2012, and the introduction of our eCommerce platform
for HTML5 in August 2012. Premium subscriptions were also impacted favorably in 2012 by an increase in marketing spending.

Collections increased by $22.9 million, from $29.6 million in 2011 to $52.5 million in 2012. This increase was due to an increase in
premium subscriptions and domain name registration sales.

Costs and Expenses

Cost of Revenues. Cost of revenues increased by $3.9 million, or 73.6%, from $5.3 million in 2011 to $9.2 million in 2012.
This increase was primarily attributable to an increase of $1.4 million in payroll expenses due to increased headcount from 73 to 114, an increase of $1.0 million in bandwidth and hosting costs, an increase of $0.9 million in domain name costs
as we started to sell third-party domain names in May 2011, and an increase of $0.6 million related to allocated overhead expenses due to expanded activities.

Research and Development. Research and development expenses increased by $2.1 million, or 14.3%, from $14.7 million in 2011 to $16.8 million in 2012. This increase was attributable to an increase
of $2.8 million in payroll and consultants fees due to increased headcount from 126 to 176 to support our development plans, which was partly offset by a decrease of $1.4 million in share-based compensation costs, and an increase of $0.7 million
related to allocated overhead expenses due to expanded activities.

Selling and Marketing. Selling and marketing
expenses increased by $7.5 million, or 34.7%, from $21.6 million in 2011 to $29.1 million in 2012. This increase was attributable to an increase of $6.0 million in user acquisition costs and other marketing activities from $16.2 million in 2011
to $22.2 million in 2012 due to the expansion of distribution channels for our products and services. It also resulted from an increase of $0.8 million in payroll expenses due to increased headcount from 44 to 56, and an increase of $0.6 million in
processing costs of our collections and an increase of $0.1 million in facilities costs.

General and Administrative.
General and administrative expenses decreased by $1.7 million, or 31.5%, from $5.4 million in 2011 to $3.7 million in 2012. This decrease was primarily attributable to a decrease of $2.1 million in payroll expenses, which included a decrease of $2.3
million in share-based compensation expenses recorded in 2011 that was partly offset by an increase of $0.2 million in payroll fees. There was also an increase of $0.4 million in external services and other costs.

Financial Income (Expenses), Net. Financial income (expenses), net increased by $0.5 million from 2011 to 2012. Financial income in
2012 was primarily due to gains from hedging transactions entered into to mitigate foreign exchange fluctuations of the NIS against the U.S. dollar. This increase was partially offset by exchange rate differences.

Taxes on Income. Taxes on income increased by $0.3 million from $0.1 million in 2011 to $0.4 million in 2012. This increase was
primarily attributable to an increase of $0.2 million in taxes in Brazil and increase of $0.1 million in taxes in the U.S.

Year Ended December 31, 2011 Compared to Year Ended December 31, 2010

Revenues. Revenues increased by $14.7 million, or 148%, from $9.9 million in 2010 to $24.6 million in 2011. The substantial
majority of this increase was attributable to the increase in premium subscriptions, with virtually no impact from changes in product pricing. The increase in premium subscription revenues was driven by a 104% growth in our premium subscriptions
from 149,084 as of December 31, 2010 to 298,143 as of December 31, 2011. This increase resulted from us more than doubling our marketing expenses from 2010 to 2011 and introducing our platform in additional languages, including French,
Italian, Portuguese and Spanish, which contributed to increased revenues.

Collections increased by $15.8 million from $13.8 million in 2010 to $29.6 million in 2011.
This increase was due to an increase in premium subscriptions and also due to sales of domain name registration sales which was introduced in May 2011.

Costs and Expenses

Cost of Revenues. Cost of revenues
increased by $3.1 million, or 140.9%, from $2.2 million in 2010 to $5.3 million in 2011. Cost of revenues increased primarily due an increase of $1.7 million in payroll expenses due to increased headcount from 42 to 73, an increase of $0.9
million related to allocated overhead due to expanded activities and an increase of $0.5 million in bandwidth and hosting costs. The increase in 2011 is attributed to our call center office which began operations in the end of 2010 and increased its
activity through 2011.

Research and Development. Research and development expenses increased by $7.4 million, or
101.4%, from $7.3 million in 2010 to $14.7 million in 2011. This increase was attributable to an increase of $6.2 in payroll and consultant fees, which includes $4.9 million due to increased headcount from 80 to 126 to support new product
initiatives and $1.3 million due to an increase in share-based and option compensation expenses. There was also an increase of $1.2 million related to facilities fee and allocated overhead expenses due to growth in headcount.

Selling and Marketing. Selling and marketing expenses increased by $11.8 million, or 120.4%, from $9.8 million in 2010 to
$21.6 million in 2011. This increase was primarily attributable to an increase of $9.7 million in user acquisition and marketing activity costs from $6.5 million in 2010 to $16.2 million in 2011 due to the expansion of our distribution channels such
as paid searches and online media buying. This increase was also due to an increase of $0.9 million due to increased payroll expenses associated with increased headcount from 36 to 44, an increase of $0.8 million in processing costs and an increase
of $0.4 million in facilities fees.

General and Administrative. General and administrative expenses increased by $3.6
million, or 200.0%, from $1.8 million in 2010 to $5.4 million in 2011. This increase was due to an increase of $2.2 million of share-based compensation expenses, as well as an increase of $0.7 million in personnel-related costs and an increase of
$0.7 million due to third-party professional services fees and overhead expenses.

Financial Income (Expenses), Net.
Financial expenses increased from 2010 to 2011 primarily due to currency hedging activities, which were partially offset by an increase in interest income on cash balances and exchange rate differences.

Taxes on Income. Taxeson income remained consistent from 2010 to 2011.

The following tables present our unaudited condensed consolidated quarterly results of operations in dollars and as a percentage of
revenues for the periods indicated. Our quarterly collections and free cash flow as well as reconciliations of revenues to collections and reconciliations of net cash used in operating activities to free cash flow for the same periods are also
presented. This information should be read in conjunction with our consolidated financial statements and related notes included elsewhere in this prospectus. The historical quarterly results presented are not necessarily indicative of the results
that may be expected for any future quarters or periods.

See SummarySummary Consolidated Financial and Other DataNon-GAAP Financial Measures for how we define and calculate collections and free cash
flow, a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP measures, and a discussion about the limitations of these non-GAAP financial measures.

Number of users at period end is defined as the total number of users, including those who purchase premium subscriptions, who are registered with Wix.com with a unique
email address at the end of the period.

Although our revenues and collections have grown quarter over quarter for the eight quarters
presented above, our net loss has fluctuated from quarter to quarter. These quarterly fluctuations in net loss result primarily from increases in selling and marketing expenses for user acquisition in order to generate revenues in subsequent
periods.

We believe there are slight seasonal impacts to our business during major holiday periods when we experience lower
than average daily site traffic. However to date, seasonal impacts have not been clearly visible in our quarterly consolidated results of operations, which we believe may be due to the rapid growth of our business and our geographic breadth. In
the future, seasonal trends may cause fluctuations in our quarterly results, including fluctuations in sequential collections.

Liquidity
and Capital Resources

Since our inception, we have financed our operations primarily through the proceeds from the
issuance of our preferred shares and cash flows from operations. As of June 30, 2013, we had $7.8 million of cash and cash equivalents. In addition, we had $2.3 million as restricted deposits of which $1.4 million related to our currency hedging
transactions and the remaining balance consisted of restricted bank deposits for our leases, credit card agreements and also reserves deposit to secure our online merchant activity with one of our billing processors.

A substantial source of our cash provided by operating activities is our deferred revenues, which is included on our consolidated balance
sheet as a liability. Deferred revenues consist of the unrecognized portion of upfront payments from our premium subscriptions as well as domain name registration sales. We assess our liquidity, in part, through an analysis of the anticipated
recognition of deferred revenues into revenues together with our other sources of liquidity. As of June 30, 2013, we had a working capital deficit of $23.2 million, which included $25.7 million of short-term deferred revenues recorded as a current
liability, and we also had $1.1 million of long-term deferred revenues. These deferred revenues remains unrecognized generally for one to 12 months for premium subscriptions and one to 36 months for domain name registration sales, and will be
recognized as revenues ratably over the term of the service period when all of the revenue recognition criteria are met in accordance with our revenue recognition policy.

While our primary source of liquidity is cash flow from operations, we also have funds available under a revolving credit facility with Silicon Valley Bank. The facility is denominated in the U.S. dollar
and has a borrowing capacity of the lower of (1) our last months eligible collections or (2) $10 million. Our eligible collections for June 2013 were $7.0 million. Any borrowings under the facility bear interest at an annual
rate equal to a daily floating prime rate, as published in the Wall Street Journal, plus 2.25%. The agreement governing the revolving credit facility contains customary terms and conditions. The agreement also contains the following negative
covenants, for which the lenders consent is required:



a commitment not to make distributions or payments to our current or former shareholders, except in the ordinary course of business or as compensation
to officers, directors and employees;

limitations on dissolution, any subordinated debt arrangement, mergers, acquisitions and dispositions not in the ordinary course of business; and



restrictions on changes in business, management, ownership or business locations, including the addition of new offices or business locations, or
changes in organizational structure.

Failure to meet these financial and other covenants would enable the
bank to demand immediate repayment of all outstanding balances under the facility. As of June 30, 2013, we were in compliance with all such covenants. All borrowings under the revolving credit facility must be repaid by December 31, 2014.
As of June 30, 2013, we had no outstanding borrowings under this credit facility.

We believe our existing cash and cash
from operations will be sufficient to fund our operations for at least the next twelve months. In addition we believe that these resources, together with borrowings under our credit facility and the net proceeds from this offering, will serve to
accelerate our growth plans and future operations.

We expect to spend approximately $2.0 million through December 31, 2013 for capital
expenditures, primarily related to leasehold improvements as we expand our office space. Our future capital requirements will depend on many factors, including our rate of revenue growth, the expansion of our selling and marketing activities, the
timing and extent of our spending on research and development efforts, and international expansion. We may also seek to invest in or acquire complementary businesses or technologies. To the extent that existing cash, cash from operations and net
proceeds from this offering are insufficient to fund our future activities, we may need to raise additional funding through debt and equity financing. Additional funds may not be available on favorable terms or at all.

Cash Used in Operating Activities

Net cash used in operating activities grew from 2010 to 2011 and decreased through 2012 and the six months ended June 30, 2013. In the six
months ended June 30, 2013, operating activities provided $1.3 million in cash. Our primary source of cash from operating activities has been cash collections from our premium subscriptions. Our primary uses of cash from operating
activities have been selling and marketing expenses, personnel and related overhead costs. The increase in cash used in operating activities from 2010 to 2011 resulted from an increase in selling and marketing expenses, research and development
activities and support costs for new users partially offset by the growth in collections from our premium subscriptions. The decrease from 2011 to 2012, as well as the positive cash from operations generated in the six months ended June 30, 2013,
was due to the significant growth in collections from our premium subscriptions. We expect cash inflows from operating activities to be affected by increases in sales and the timing of collections. We expect cash outflows from operating activities
to be affected by increases in marketing and increases in personnel costs as we grow our business.

For the six months ended
June 30, 2013, operating activities provided $1.3 million in cash. Despite generating positive cashflow, our operating cash needs resulted primarily from our net loss of $10.1 million, which included $2.0 million of non-cash charges related
primarily to share-based compensation expenses, depreciation and tax benefits related to the exercise of share options. Our net loss (after adjusting for such non-cash items) was offset primarily by a net change of $9.4 in our operating assets and
liabilities, which was primarily the result of an increase of $7.9 million in deferred revenues due to an increase in collections from our premium subscriptions and a $3.5 million increase in payroll accruals and other liabilities primarily due to
trade payables and others. These increases were offset by a $1.6 million increase in prepaid expenses and other current and long term assets as a result of growth in our business and a $0.4 million increase in trade receivables due to an increase in
sales.

For the six months ended June 30, 2012, operating activities used $2.8 million in cash, primarily as a result of our
net loss of $7.8 million, offset by non-cash charges of $0.9 million as well as a net change of $4.1 million in our net operating assets and liabilities. Non-cash charges included share-based compensation expenses, depreciation and tax benefits
related to the exercise of share options.

For the year ended December 31, 2012, operating activities used $3.6 million in
cash, primarily as a result of a net loss of $15.0 million, offset by non-cash charges of $2.1 million as well as a net change of $9.3 million in our net operating assets and liabilities. Non-cash charges included share-based compensation expenses,
depreciation, deferred income taxes, net and tax benefits related to the exercise of share options. The net change in our operating assets and liabilities was primarily the result of an increase of $8.8 million in deferred revenues due to an
increase in collections from our premium subscriptions and a $2.4 million increase in payroll accruals and other liabilities primarily due to trade payables and others. These increases were offset by a $0.6 million increase in trade receivables due
to an increase in sales and a $1.3 million increase in prepaid expenses and other current and long term assets as a result of growth in our business.

For the year ended December 31, 2011, operating activities used $10.6 million in cash
as a result of a net loss of $22.7 million, partially offset by non-cash charges of $5.4 million as well as a net change of $6.7 million in our net operating assets and liabilities. Non-cash charges included share-based compensation expenses,
depreciation, tax benefits related to the exercise of share options, deferred income taxes, net and capital loss. The net change in our operating assets and liabilities was primarily the result of a $5.0 million increase in deferred revenues mainly
due to an increase in sales of premium subscriptions, as well as a $2.9 million increase in accrued and other liabilities as a result of growing our business. These increases were partially offset by a $1.0 million increase in prepaid expenses and
other assets as a result of growth in our business and a $0.2 million increase in trade receivables due to an increase in sales.

For the year ended December 31, 2010, operating activities used $5.3 million in cash as a result of a net loss of $11.5 million,
partially offset by a net change of $5.0 million in our net operating assets and liabilities, as well as non-cash charges of $1.2 million.

Cash Provided by (Used in) Investing Activities

Cash used in
investing activities was $0.8 million in the six months ended June 30, 2013. Cash provided by investing activities was $0.7 million in 2012. Cash used in investing activities was $1.8 million and $4.6 million in 2010 and 2011, respectively.
Investing activities have consisted primarily of investment and proceeds of restricted deposits and purchase of property and equipment.

Cash Provided by Financing Activities

Our financing activities have primarily
consisted of proceeds from the issuance and sale of preferred shares and proceeds from the exercise of share options. For the six months ended June 30, 2013 and the years ended December 31, 2010, 2011 and 2012, financing activities provided
$0.1 million, $10.1 million, $21.0 million and $0.1 million in cash, respectively, primarily as a result of net proceeds from the issuance and sale of preferred shares and proceeds from the exercise of share options. We expect the completion of
this offering to result in a material increase in our cash flows from financing activities.

Application of Critical
Accounting Policies and Estimates

Our accounting policies and their effect on our financial condition and results of
operations are more fully described in our consolidated financial statements included elsewhere in this prospectus. We have prepared our financial statements in conformity with U.S. GAAP, which requires management to make estimates and assumptions
that in certain circumstances affect the reported amounts of assets and liabilities, revenues and expenses and disclosure of contingent assets and liabilities. These estimates are prepared using our best judgment, after considering past and current
events and economic conditions. While management believes the factors evaluated provide a meaningful basis for establishing and applying sound accounting policies, management cannot guarantee that the estimates will always be consistent with actual
results. In addition, certain information relied upon by us in preparing such estimates includes internally generated financial and operating information, external market information, when available, and when necessary, information obtained from
consultations with third-parties. Actual results could differ from these estimates and could have a material adverse effect on our reported results. See Risk Factors for a discussion of the possible risks which may affect these
estimates.

We believe that the accounting policies discussed below are critical to our financial
results and to the understanding of our past and future performance, as these policies relate to the more significant areas involving managements estimates and assumptions. We consider an accounting estimate to be critical if: (1) it
requires us to make assumptions because information was not available at the time or it included matters that were highly uncertain at the time we were making our estimate; and (2) changes in the estimate could have a material impact on our
financial condition or results of operations.

Revenue Recognition

We derive most of our revenues from monthly and annual premium subscriptions. We derive a portion of our revenues from selling third-party
domain registration. We also derive a portion of our revenues from our App Market consisting of revenues derived from sharing agreements with third parties pursuant to which we receive a portion of the collected revenues of any app to which our
users subscribe.

We recognize revenues in accordance with ASC No. 605-10-S99, (SEC Staff Accounting Bulletin No. 104,
Revenue Recognition), when (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred or services have been rendered to the customer, (iii) the fee is fixed or determinable, and (iv) collectability is reasonably
assured.

Revenues related to services for websites and the purchase and registration of domain names are recognized ratably
over the term of the service period. Revenues related to apps developed by third-party developers are recognized when earned. We account for such sales on a net basis by recognizing the commission we retain from each sale. The portion of the gross
amount billed to users that is remitted by us to third-party app developers is not reflected in our consolidated statements of operations.

We offer new premium subscription packages for a 14-day trial period during which the user can cancel the subscription at any time and receive a full refund. We consider such amounts collected from new
premium subscriptions as customer deposits until the end of the 14-day trial period. After the 14-day trial period has ended, we recognize premium subscription revenues ratably over the term of the service period, either monthly or annually. We do
not offer trial periods for domain name registrations. Deferred service revenues primarily include unearned amounts received from customers but not recognized as revenues.

Although in general, we do not grant rights of refund, there are certain instances where such refunds occur. Since we collect most of our revenues through online credit card billing, a small portion of
our users elect to chargeback due to disputes over the credit card statements and/or claims of false transaction, and accordingly ask for refunds. We maintain a provision for chargebacks and refunds in accordance with ASC No. 605, Revenue
Recognition, which we estimate based primarily on historical experience as well as management judgment and is recorded through a reduction of revenues.

A portion of our revenue transactions include multiple elements within a single contract if it is determined that multiple units of accounting exist. Commencing January 1, 2011, we adopted Accounting
Standards Update (ASU) No. 2009-13, Multiple-Deliverable Revenue Arrangements, (amendments to ASC Topic 605, Revenue Recognition) (ASU No. 2009-13). ASU No. 2009-13 requires entities to allocate revenue in an arrangement
using estimated selling prices of the delivered goods and services based on a selling price hierarchy. The amendments eliminate the residual method of revenue allocation and require revenue to be allocated using the relative selling price method.

The primary types of transactions in which we engage for which ASU No. 2009-13 is applicable are agreements that include
multiple elements which are delivered at different points in time. Such elements may include some or all of the following:

We consider the sale of each of the above stated elements in bundled agreement to be a
separate unit of accounting for the arrangement and defer the relative sales price of the undelivered element to the period in which revenue is earned.

Pursuant to the guidance under ASU No. 2009-13, when a sales arrangement contains multiple elements, the Company allocates revenue to each element based on a selling price hierarchy. The selling price for
a deliverable is based on its VSOE if available, third-party evidence (TPE) if VSOE is not available, or estimated selling price (ESP) if neither VSOE nor TPE is available. VSOE of selling price is based on the price charged
when the element is sold separately. In determining VSOE, it is required that a substantial majority of the selling prices fall within a reasonable range based on historical discounting trends for specific services. TPE of selling price is
established by evaluating largely interchangeable competitor services in stand-alone sales to similarly situated customers.

Monthly and annual premium subscriptions and domain name registrations are sold separately and therefore the selling price is based on
VSOE.

Share-Based Compensation

Under U.S. GAAP, we account for our share-based compensation for employees in accordance with the provisions of the Financial Accounting Standards Boards Accounting Standards Codification Topic 718
CompensationStock Based Compensation, which requires us to measure the cost of options based on the fair value of the award on the grant date. The Company also applies ASC 718 Compensation  Stock Compensation
(ASC No. 718) and ASC No. 505-50 Equity Based Payments to Non-Employees (ASC No. 505-50) with respect to options issued to non-employees consultants.

We selected the Black-Scholes-Merton option pricing model as the most appropriate method for determining the estimated fair value of our
share-based awards. The resulting cost of an equity incentive award is recognized as an expense over the requisite service period of the award, which is usually the vesting period. We recognize compensation expense over the vesting period using the
straight-line method and classify these amounts in the consolidated financial statements based on the department to which the related employee reports.

Option Valuations

The determination of the grant date fair value of
options using an option pricing model is affected by estimates and assumptions regarding a number of complex and subjective variables. These variables include the expected volatility of our share price over the expected term of the options, share
option exercise and cancellation behaviors, risk-free interest rates and expected dividends, which are estimated as follows:

Fair Value of our Ordinary Shares. Because our shares are not publicly traded, we must estimate the fair value of ordinary shares, as discussed
in Ordinary Share Valuations below.



Expected Term. The expected term of options granted represents the period of time that options granted are expected to be outstanding, and is
determined based on the simplified method in accordance with ASC No. 718-10-S99-1, (SAB No. 110), as adequate historical experience is not available to provide a reasonable estimate.



Volatility. The expected share price volatility was based on the historical equity volatility of the ordinary shares of comparable companies
that are publicly traded.



Risk-free Rate. The risk-free interest rate is based on the yield from U.S. Treasury zero-coupon bonds with a term equivalent to the contractual
life of the options.



Dividend Yield. We have never declared or paid any cash dividends and do not presently plan to pay cash dividends in the foreseeable future.
Consequently, we used an expected dividend yield of zero.

If any of the assumptions used in the Black-Scholes-Merton model change significantly,
share-based compensation for future awards may differ materially compared with the awards granted previously.

Based on the assumed initial public offering price of $
per share, the midpoint of the estimated initial public offering price range, set forth on the cover page of this prospectus, the intrinsic value of the awards outstanding as of June 30, 2013 was
$ million, of which $ million related to vested options and $ million related to unvested options.

Ordinary Share Valuations

Due to the absence of an active market for our ordinary shares, the fair value of our ordinary shares for purposes of determining the exercise price for award grants was determined in good faith by our
management and approved by our board of directors. In connection with preparing our financial statements for this offering, our management considered the fair value of our ordinary shares based on a number of objective and subjective factors
consistent with the methodologies outlined in the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation, referred to as the AICPA Practice Aid, including:



the likelihood of achieving a liquidity event, such as an initial public offering, given prevailing market conditions and the potential effect of such
event on our stock price

the market performance of publicly traded companies in the web services space; and



external market conditions affecting the web services space.

For the purpose of the valuation referred to above, we used the discounted cash flow method to determine our enterprise value. Using this method, our projected after-tax cash flows available to return to
holders of invested capital are discounted back to present value, using the discount rate. The discount rate, known as the weighted cost of capital, accounts for the time value of money and the appropriate degree of risks inherent in the business.

We determined our enterprise value, and allocated that enterprise value to each element of our capital structure (preferred
shares, ordinary shares and options), using two methodologies:



First, we determined our enterprise value based on a fully diluted scenario where all preferred shares convert into ordinary shares in an exit scenario
due to a liquidity event, such as an initial public offering, or IPO. In this scenario, we based our enterprise value on the most recent investment round prior to the valuation (where such investment round occurred sufficient recently) or otherwise
used a combination of the guideline company method and information based on our preliminary discussions with the underwriters. For the guideline company method, we identified public companies that we determined had business and financial risks
comparable to us. We considered the enterprise value to revenue multiple and enterprise value to EBITDA multiple of those comparable companies to derive our enterprise value. The enterprise value was then divided by the resulting number of shares to
determine a per share value.



Second, we determined our enterprise value based an assumed liquidity scenario in which the preferred stock benefitted from its liquidation preference,
such as a sale, merger or liquidation. We used the discounted cash flow, or DCF, method to determine our enterprise value, and the option pricing methodology, or OPM to allocate it to each element of our capital structure.



Under the DCF, our projected after-tax cash flows available to return to holders of invested capital were discounted back to present value, using the
discount rate. The discount rate, known as the weighted cost of capital, accounts for the time value of money and the appropriate degree of risk inherent in a business.



Under the OPM, ordinary and preferred shares are treated as call options, with the preferred shares having an exercise price based on the liquidation
preference of the preferred shares. Ordinary shares will only have value if funds available for distribution to the shareholders exceed the value of the liquidation preference at the time of a liquidity event such as a merger, sale or initial public
offering, assuming the enterprise has funds available to make a liquidation preference meaningful and collectible to the shareholders. The ordinary shares are modeled as call options with a meaningful enterprise at an exercise price equal to the
remaining value immediately after the convertible preferred shares are liquidated. The value of the call options is determined using the Black Sholes option-pricing model.

Each valuation scenario under the full dilution scenario and liquidity event scenario was then assigned a probability weighting based on
managements discussions with our board of directors and our assessment of market conditions under the Probability Weighed Expected Return Method (PWERM). The valuation is then discounted due to factors such as marketability and restrictions on
shares.

We have set out below the application of the above methodologies to the valuation of our
ordinary shares on each of the grant dates:



March 2012 Grant. We determined that the fair value of our ordinary shares as of March 1, 2012 was $7.47 per share. As part of this
determination, along with market considerations, our management considered a third-party valuation dated March 22, 2013.



For the purpose of the fully diluted scenario, we used the enterprise value derived from the purchase at arms length of our Series E preferred
shares pursuant to an agreement entered into in February 2011. In considering the appropriateness of using this enterprise value, we considered the fact that it reflected a higher enterprise value than would be obtained as of March 2012 using the
guideline public company method based on 12 months trailing revenue or 2013 projected revenue and that no significant events had occurred since February 2011 either to our business, or valuation of the comparable companies, that would lead to a
conclusion that our enterprise value had declined since the February 2011 investment. This resulted in a value per ordinary share of $20.48. We believe that the $20.48 ordinary share value under the fully diluted scenario reflected the value that
investors perceived we might achieve in a future exit event and not just our going concern value.



For the purpose of the liquidity scenario, we used a discount rate of 21.9%. The resulting enterprise value was allocated among the elements of our
capital structure using the OPM assuming a liquidity event in 2.5 years. This resulted in a value per ordinary share of $8.10.

Using the PWERM, we then estimated that the probability of the fully diluted scenario was 10%, while the probability of the liquidity scenario was 90%. Applying these weightings, we arrived at a value of
$9.34 per ordinary share, which we discounted by 20% due to lack of marketability, to arrive at a fair value of $7.47 per share.



May 2012 Grant. In reviewing the grant made in May 2012, our management considered the valuation analyses conducted in March 2012 and August
2012, and concluded that the continued development of our business made it appropriate to apply a value of $9.09 per ordinary shares based on a straight line approach between those two valuations. Specifically, we launched our HTML5 platform at the
end of March 2012. While no negative events were reported, we did not have assurance of widespread market success in May 2012. Accordingly, we determined that the reasonable approach was to take the estimated fair value based on the linear
progression of the two valuations to reflect the ongoing growth of our business.



August 2012 Grant. We determined that the fair value of our ordinary shares as of August 1, 2012 was $11.29 per share. As part of this
determination, along with market considerations, our management considered a third-party valuation analysis dated March 22, 2013.



For the purpose of the fully diluted scenario, we continued to use the enterprise value derived from the purchase at arms length of our Series E
preferred stock pursuant to an agreement entered into in February 2011. Our reasons as to the appropriateness of using this valuation were the same as in March 2012. This resulted in a value per ordinary share of $20.48.



For the purpose of the liquidity scenario, we used a discount rate of 20.5%. The reason for the decrease compared to March 2012 was the later stage of
development of our company and a decrease in the interest rate of 20-year Treasury bills. The resulting enterprise value was allocated among the elements of our capital structure using the OPM assuming a liquidity event in 1.08 years. This resulted
in a value per ordinary share of $10.88.

Using the PWERM, we then estimated that the probability of the fully diluted
scenario was 25%, while the probability of the liquidity scenario was 75%. Applying these weightings, we arrived at a value of $13.28 per ordinary share, which we discounted by 15% due to lack of marketability, to arrive at a fair value of $11.29
per share. The reason for the decrease in the discount for lack of marketability compared to March 2012 was a shorter time horizon until an IPO and decreased market volatility.



January 2013 Grant. We determined that the fair value of our ordinary shares as of January 9, 2013 was $17.39 per share. As part of this
determination, along with market considerations, our management considered a third-party valuation analysis dated May 7, 2013.



For the purpose of the fully diluted scenario, we used the guideline company method to determine our enterprise value. At that time, we were discussing
the possibility of an IPO with investment banks and planned to commence such a process in the coming months. Therefore, we decided that it was not appropriate to continue to use the February 2011 enterprise value, but that we should use a valuation
methodology similar to those that the investment banks and potential investors in an IPO would use, such as the guideline company method. We used a 6.0 multiple of enterprise value to trailing 12 months revenue, a 3.5 multiple of enterprise value to
projected 2013 revenue and a 10.0 multiple of enterprise value to projected 2015 EBITDA. This resulted in a value per ordinary share of $23.71.



For the purpose of the liquidity scenario, we used a discount rate of 20% for the DCF method, which was substantially identical to the discount rate
used in August 2012. The resulting enterprise value was allocated among the elements of our capital structure using the OPM assuming a liquidity event in 0.98 years. This resulted in a value per ordinary share of $17.22. The reason for the
significant increase in our value under the liquidity scenario was that our projected results of operations had improved significantly since we had last determined our value using the DCF method. Our HTML5 platform had been launched over
10 months before and we had seen its impact on our user base. As a result, we increased our financial projections materially.

Using the PWERM, we then estimated that the probability of the fully diluted scenario was 50% as we had begun to contemplate an IPO. The probability of a liquidity scenario was thus estimated at 50%.
Applying these weightings, we arrived at a value of $20.46 per ordinary share, which we discounted by 15% due to lack of marketability, to arrive at a final value of $17.39 per share.



May 2013 Grant. We determined that the fair value of our ordinary shares as of May 2, 2013 was $27.00 per share. As part of this
determination, along with market considerations, our management considered a third-party valuation analysis dated August 13, 2013.



For the purpose of the fully diluted scenario, we considered the preliminary valuation discussions that we had held with the underwriters in April 2013
assuming an IPO in the fourth quarter of 2013. This resulted in an estimated fair value per ordinary share of $37.35 after discounting to present value the preliminary estimated IPO valuation. We then used the guideline company method in order to
test the reasonableness of this fair value. The resulting revenue multiples were above the range of historical market participant guideline revenue multiples, but within the range of market participant guideline multiples based upon projected
performance. Our multiples of projected EBITDA were above the market participant range in 2016, and within the market participant range in 2017. These results were considered reasonable reflecting the fact that we are at an earlier stage of our
development, but growing more rapidly than market participant guideline companies.



For the purpose of the liquidity scenario, we used a discount rate of 17% for the DCF method. We then used the guideline company method in order to
test the reasonableness of the resulting fair value. Our revenue multiples were within the ranges of market participant guideline revenue multiples for 2012 and 2013, and slightly below for 2014 and 2015. Our EBITDA multiples for 2016 and 2017 were
within the market participant ranges. These results were considered

reasonable based on the considerations described above. The resulting enterprise value was allocated among the elements of our capital structure using the OPM assuming a liquidity event in 1.67
years, which was approximately one year later than the projected IPO should the latter not occur. This resulted in a value per ordinary share of $19.29.

Using the PWERM, we then estimated that the probability of the fully diluted scenario was 65% as we were already in the
process of preparing for an IPO. The probability of a liquidity scenario was thus estimated at 35%. Applying these weightings, we arrived at a value of $31.03 per ordinary share, which we discounted by 13% due to lack of marketability, to arrive at
a fair value of $27.00 per share.



July 2013 Grant. We determined that the fair value of our ordinary shares as of July 11, 2013 was $30.35 per share. As part of this
determination, and along with market considerations, our management considered a third-party valuation analysis dated August 13, 2013.



For the purpose of the fully diluted scenario, we considered the further preliminary valuation discussions that we had held with the underwriters in
April 2013 assuming an IPO in the fourth quarter of 2013. This resulted in an estimated fair value per ordinary share of $40.79 after discounting to present value the preliminary estimated IPO valuation. We then used the guideline company method in
order to test the reasonableness of this fair value. In connection with the DCF method. Our resulting revenue multiples were above the range of historical market participant guideline revenue multiples, but within the range of market participant
guideline multiples based upon projected performance. Our EBITDA multiples for 2016 were above the market participant ranges and within the market participant range for 2017. These results were considered reasonable reflecting the fact that we are
at an earlier stage of our development, but growing more rapidly than the market participant guideline companies.



For the purpose of the liquidity scenario, we used a discount rate of 16% in connection with the DCF method, which was substantially identical to the
discount rate used in May 2013. We then used the guideline company method in order to test the reasonableness of the resulting fair value. Our revenue multiples were within the ranges of the market participants for all periods tested (2012, 2013,
2014 and 2015). Our EBITDA multiples for 2016 and 2017 were within or near the market participant ranges. These results were considered reasonable based on the considerations described above. The resulting enterprise value was allocated among the
elements of our capital structure using the OPM assuming a liquidity event in 1.47 years. This resulted in a value per ordinary share of $23.36.

Using the PWERM, we then estimated that the probability of an IPO under each of the fully diluted scenario was 65%, the
same as in May 2013. The probability of a liquidity scenario was thus estimated at 35%. Applying these weightings, we arrived at a value of $34.69 per ordinary share, which we discounted by 12.5% due to lack of marketability, to arrive at a final
value of $30.35 per share. We compared this value against the value paid for a recent third party, arms-length sale of a small number of our ordinary shares and found them to be substantially identical.



August 2013 Grant. In reviewing the grant made in August 2013, our management considered the valuation analysis as of July 11, 2013, and
concluded that, as no significant developments had occurred in our business from July 11, 2013 to August 13, 2013, it was appropriate to continue to use a fair value of $30.35 per ordinary share for all grants made.

Derivatives and Hedging

We account for derivatives and hedging based on ASC 815 Derivatives and Hedging, which requires us to recognize all derivatives on the balance sheet at their fair value. We do not meet the
definitions of the pronouncement regarding designated and effective hedging and as result gains and losses related to such derivative instruments are recorded in financial income (expenses), net.

As part of the process of preparing our consolidated financial statements we are required to estimate our taxes in each of the
jurisdictions in which we operate. We estimate actual current tax exposure together with assessing temporary differences resulting from differing treatment of items, such as accruals and allowances not currently deductible for tax purposes. These
differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheets. We must assess the likelihood that our deferred tax assets will be recovered from future taxable income and to the extent we believe
that recovery is not likely, we must establish a valuation allowance.

Management must exercise significant judgment to
determine our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. We base the valuation allowance on our estimates of taxable income in each jurisdiction in
which we operate and the period over which our deferred tax assets are more likely than not to be recoverable. As of December 31, 2012, we had a net operating loss carryforward of approximately $36.7 million and had recorded a valuation
allowance against most of our net deferred tax assets, based on the available evidence, we believed at that time it was more likely than not that we would not be able to utilize all of these deferred tax assets in the future.

U.S. GAAP requires that the impact of an uncertain income tax position on the income tax return is recognized at the largest amount that
is more likely than not to be sustained upon audit by the relevant tax authority. If we ultimately determine that the payment of these liabilities will be unnecessary, we reverse the liability and recognize a tax benefit during that period.
Conversely, we should then record additional tax charges in a period in which we determine that a recorded tax liability is less than we expect the ultimate assessment to be. We did not recognize any significant unrecognized tax benefits during the
periods presented in this prospectus.

Off-Balance Sheet Arrangements

We do not currently engage in off-balance sheet financing arrangements. In addition, we do not have any interest in entities referred to
as variable interest entities, which includes special purposes entities and other structured finance entities.

Quantitative and
Qualitative Disclosure about Market Risk

Foreign Currency Risk

Our results of operations and cash flows are affected by fluctuations due to changes in foreign currency exchange rates. In 2012, 89% of
our revenues were denominated in U.S. dollars and 11% in other currencies, primarily in euros. In 2012, 58% of our cost of revenues and operating expenses were denominated in U.S. dollars and 42% in NIS. Our NIS-denominated expenses consist
primarily of personnel and overhead costs. Since significant portions of our expenses are incurred in NIS, any appreciation of the NIS relative to the U.S. dollar would adversely impact our net loss or net income (if any).

Our primary processing provider converts payments collected from by our premium users in British pound- and Euro-denominated payments to
us into U.S. dollars in consideration for the payment of an additional fee; however, since the original payment are not received in dollars this does not overall reduce our exposure to exchange rate fluctuations between these currencies and the U.S.
dollar.

The following table presents information about the changes in the exchange rates of the NIS against the U.S. dollar:

The figures above represent the change in the average exchange rate in the given period
compared to the average exchange rate in the immediately preceding period. Negative figures represent depreciation of the U.S. dollar compared to the NIS.

A 10% increase (decrease) in the value of the NIS against the U.S. dollar would have decreased (increased) our net loss by approximately $2.5 million in 2012.

To protect against the increase in value of forecasted foreign currency cash flow resulting from expenses paid in NIS during the year, we
have instituted a foreign currency cash flow hedging program. We hedge limited portions of the anticipated payroll of our Israeli employees, Israeli suppliers and anticipated rent expenses of our Israeli premises denominated in NIS for a period of
one to twelve months with forward contracts and other derivative instruments.

Our results of operations may also be impacted
by currency translation gains and losses on monetary assets and liabilities, primarily cash and cash equivalents and restricted deposits denominated in currencies other than the U.S. dollar. Any such gains or losses only impact the dollar value of
our non-dollar denominated cash and cash equivalents and restricted deposits and result from changes in reported values due to exchange rate fluctuations between the beginning and the end of reporting periods. As of June 30, 2013, we had
$2.4 million and $1.7 million in cash and cash equivalents and restricted deposits denominated in NIS and the Brazilian real, respectively, while we had $6.0 million denominated in U.S. dollars.

Other Market Risks

We do not believe that we have material exposure to interest rate risk due to the fact that we have no long-term borrowings.

We do not believe that we have any material exposure to inflationary risks.

New and Revised
Financial Accounting Standards

The JOBS Act permits emerging growth companies such as us to delay adopting new or revised
accounting standards until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this and, therefore, we will be subject to the same new or revised accounting standards as other public
companies that are not emerging growth companies.

Recently Issued and Adopted Accounting Pronouncements

In December 2011, the Financial Accounting Standards Board, or FASB, issued ASU No. 2011-11, Balance Sheet (210):
Disclosures about Offsetting Assets and Liabilities, which requires additional disclosures about the nature of an entitys rights of setoff and related arrangements associated with its financial instruments and derivative instruments. The
disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods therein, with retrospective application required. In January 2013, the FASB issued Accounting Standard Update
No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. We believe that the adoption of both the standard and the update will not have a material impact on our consolidated financial statements.

We believe that
the Internet should be accessible to everyone, not just to access information but also to develop, create and contribute.

We
see many similarities in our vision with the desktop revolution, when computer hardware and software evolved to provide everyone with the capability to develop, create and print professional-quality documents from their desktop. Access expanded to
everyone, document creation became a core human skill, and the asset-heavy approach was abandoned. This same revolution has not yet happened online. Today, professional skill and capital is needed to turn ideas into high-quality web content. We
believe that by providing an easy-to-use and affordable solution with professional-quality results, we are leading the Webtop Revolution.

Industry Overview and Market
Opportunity

Increasing need for a dynamic digital presence

According to a June 2013 Netcraft survey, there are more than 673 million websites across all domains, nearly four times the number that
existed five years ago. 79 million of these websites were added in 2012 alone. The way that consumers interact with websites, however, continues to expand with the evolution of technology. Consumers have come to expect a high level of
personalization, engagement and functionality; a static website is no longer satisfactory and can even negatively affect overall brand perception for businesses, organizations and professionals.

In the current market, businesses, organizations and professionals need a dynamic digital presence with tools to manage interactions with
customers, suppliers, partners and employees online and in real time. These interactions include back-end activities like invoicing, customer relationship management and payment processing, as well as front-end activities such as communications,
online marketing, reservations and scheduling, and social media integration.

Use of dynamic web content and services for high
level customer engagement is becoming increasingly prolific. For example:



more than 113 million diners were seated through reservations made through OpenTable, a leading online restaurant reservation website, in 2012;



more than 108 million unique visitors visited Yelp, a leading local business information and review website, to find ratings and reviews of local
businesses in the second quarter of 2013; and



more than 7.6 million payments are processed through PayPal, a leading payments and eCommerce business, every day.

Businesses, organizations and professionals that have access to the latest technology and large budgets are able to create this fully
functional, integrated and engaging digital presence and widen the competitive gap between themselves and those that lack access.

Creating a dynamic digital presence is challenging

Building this
presence is becoming more challenging for businesses, organizations, professionals and individuals for the following reasons:



Developing a dynamic digital presence with professional quality is expensive. As an extension of the brand, a business website needs to be
professional-quality and provide the owner with creative tools to customize to its unique specifications. Developing and maintaining a professional-quality digital presence today often requires hiring professional designers and developers, which is
not an option for many small businesses with limited budgets.



Learning to code is difficult, time consuming and out of reach for most. While basic website building solutions are available to those with
limited needs, creating a professional-quality digital presence typically requires time and effort to learn coding languages. As these languages continue to evolve over

time to allow for additional features and functionality, such as the recent launch of HTML5, the complexity and level of skill required to develop a digital presence increases dramatically. As a
result, these professional-quality improvements are generally out of reach for those that have no experience with computer programming.



The ability to manage and modify in real time is limited and time consuming. Managing a web presence often requires regular
updates, editing and real time changes. Adding newly-created workflow tools to a site requires changes to the sites content and layout. Making these modifications typically requires the ability to edit code, which requires most businesses,
organizations, professionals and individuals to hire a professional. Hiring a third-party to dynamically update a site is costly, impractical and often means even small changes take a significant amount of time. Most website template solutions
provide options, but have very limited flexibility, in terms of what can be changed once a website is published.



Integrating functionality requires advanced skills and access to multiple vendors. Proficiently managing and integrating multiple applications
and tools such as payment processing, eCommerce capabilities and online marketing is complex. There are a wide variety of point solutions available from many different vendors which can further complicate the process. Discovering which solutions are
available and then finding the best-fit solutions is time consuming and can be confusing. Once solutions are found, integrating them in a way that maintains structural, permission, and access controlsboth within a website and between
applicationstypically requires the hiring of costly developers.



There are many platforms, browsers and devices which each have different compatibility requirements. There are a large and growing number of
platforms, browsers, and devices that are used to access the Internet. Each of these has different design and compatibility requirements, ranging from screen size to coding language to security features. In order to develop a digital presence that
is widely accessible, there is often a need to recreate an entire site multiple times with different specifications. This is costly and time consuming for even the largest companies.

We believe there is a significant opportunity to provide an elegant solution that caters to the accelerating demands of businesses,
organizations, professionals and individuals who need to create and manage a dynamic, professional digital presence at a reasonable cost.

From registration on Wix.com to publishing and
maintaining a digital presence, we offer a simple and code-free web development platform supported by our customer service experts at every step in the process:

Organic sources of traffic means traffic to our website in respect of which there is no direct cost to us associated with such source of traffic, which includes but are
not limited to: (i) clicks on unpaid links which navigate directly to our homepage, (ii) clicks on a non-paid Wix advertisement banner on a Wix free site, and (iii) Search Engine Optimization, which refers to the way in which we develop our site to
improve our ranking on search engines when a relevant search engine query that does not contain the term Wix is entered.

(2)

Paid sources of traffic means traffic to our website in respect of which there is a direct cost to us associated with such source of traffic, which includes but are not
limited to: (i) Search Engine Marketing, which refers to pay-per-click links to our website generated in search engine results for which we pay a fee to the search engine, (ii) banner ads that we pay for on various websites, and (iii) advertisements
we pay for on social networking sites.

Benefits to Our Users

We believe that our solution provides the following key benefits to our users:



Professional quality at an affordable price. We provide customizable and professionally designed content so anyone can develop a high quality
digital presence, without the need for design or coding skills. We are committed to providing high quality design elements and features so users can create a digital presence that encapsulates their vision, serves their brand and establishes their
credibility. As of June 30, 2013, we had a dedicated team of over 40 design professionals, whose deep understanding of web design trends is reflected in hundreds of website templates catering to a wide variety of business verticals. Users may access
our professional content and features at a material discount to the cost of hiring a professional or in many cases at no cost at all.



Easy-to-use technology. Our platform provides our users with a powerful and easy-to-use cloud-based solution that takes the technological
complexity out of web development and management, allowing anyone to have a dynamic digital presence. Our drag-and-drop editing environment enables users with basic computer skills to create a fully functional digital presence without the need to
develop an advanced new skill set.



User-driven website management. Our cloud-based platform makes ongoing management simple, enabling users to maintain their dynamic digital
presence at any time. For example, retailers can post seasonal or one time promotions, artists can update portfolios and individuals can post new photos, all without the need to pay for expensive design professionals and wait for them to make small
changes. We also have an in-house team of 130 support and call center professionals available for our users.



Access to third-party apps.We offer a selection of over 140 free and paid apps providing online workflow and management tools
that users can add through the Wix Editor, from maps and contact forms to email and newsletters. We help users find and discover apps that are relevant and useful to them. Users can simply select apps and drag-and-drop them into their websites,
enabling them to manage their digital presence in one place. Our proprietary software manages any coding required without any effort needed by the user, making integration with our users sites seamless. This means that permissions and controls
with the site are managed automatically, as are integrations between apps. In addition, we allow users to connect to a variety of tools and services across the web, such as Facebook, Twitter, Yelp, and OpenTable.



Multi-platform. Our technology addresses the challenges posed by the wide range of browsers and devices used to access the web. With our HTML5
builder, Wix users can create websites that are adaptable and of same quality regardless of the device or browser with which they are accessed. In addition, we handle all the code customizations required to maintain and be responsive to a dynamic
market with rapidly changing technologies. As technologies, browsers and specifications change, we update our editing environment so our users are not impacted. Our multi-platform approach removes additional costs associated with the need to develop
sites compatible with new device and browser platforms.

We believe that our solution offers the following key benefits to our partners:



Distribution to a large user base. Our large user base of more than 37 million users consists of small businesses, organizations,
professionals and individuals that provide us with valuable insight into their behavior. We attract interest from multiple companies seeking to market their solutions effectively to this large and highly engaged audience through free and paid apps
available in our App Market, as well as other offers, features and services. We also offer data to our partners on the engagement and use of their solutions that are offered through our platform, providing our partners with valuable feedback.



Seamless integration of offered solutions.We help developers get their products discovered and provide easy installation and
integration. We require that all solutions or apps offered by our partners are compatible with our platform, which enables easy integration for our users. This integration ensures our partners solutions will not require additional coding or
advanced skills in order to work on our platform. We collect payments from our users for paid apps, further reducing friction for both our users and our partners.

Our Strengths

We believe the following key strengths provide us with
competitive advantages:



Proprietary technology platform. Our core strength is our technology that reduces the challenges and complexities of web development and
management for our users. Our environment enables simple drag-and-drop capabilities that are used to build sophisticated websites. Our technology uses HTML5, the most advanced markup language available, which gives our users the ability to
easily incorporate video, audio, fonts, graphics and animations into their site. Our users also benefit from enhanced workflow functionalities through the seamless integration of third-party apps, which can be purchased in our App Market. In
addition, we have a culture of innovation, meaning our developers are constantly working on finding and developing new solutions to improve the quality of our product and the breadth of our platform.



Large user base and growing global ecosystem.As of August 31, 2013, we had more than 37 million users across 190 countries.
We currently offer our platform in several languages in order to empower our users to create and manage a digital presence in their own language. Our users often become Wix advocates, recommending us to their communities, building sites for their
friends, or using the platform to launch their own web development business. As the Wix user base and community grows, we become increasingly valuable as a distribution channel for partners and developers, who in turn expand our offering to our
users with additional features and services through the development of additional apps.



Superior design and content. One of our core focuses is developing high quality design elements for our users. As a result, more than 10% of our
workforce is comprised of designers. We believe that our investment in design, which allows our users to create a visually engaging and professional-quality digital presence, sets us apart. Because we provide our users with a superior web design
starting point, including easily editable layouts with dynamic galleries, graphics, color-palettes, and fonts, we believe we attract users that have a higher likelihood of subscribing to our services and renewing at regular intervals.



Efficient marketing and customer acquisition.Our marketing activities are based on a constant analysis of behavior response data
generated on our platform. This enables us to operate different marketing campaigns efficiently across a variety of advertising channels. Based on this deep comprehension of acquisition and retention channels, we have been able to grow our user base
without a direct sales force.



Embedded solution for our users. Because our solution provides the base platform for businesses to operate, Wix becomes a core aspect of our
users business, enabling them to run their business online. Our solutions are designed to cater to the varying needs of most business categories while supporting users throughout the evolution of their business lifecycle, greatly increasing
the likelihood that they

remain users. We offer our users the ability to customize our offerings to fit the specific need of their business, and we curate apps specifically designed for each type of user. We also offer
vertically-focused packages and applications specifically designed for various types of businesses, including, but not limited to, restaurants, health and beauty businesses and eCommerce sites.

Our Strategy

Key
elements of our strategy include:



Growing our user base. The value of our platform continues to increase as our user base expands. Growth of our user base is generally a leading
driver and indicator of the growth of the number of our premium subscriptions. We intend to continue to build our user base in the following ways:



Leveraging our data to increase and optimize our paid marketing. Since Wix was launched, we have generated large quantities of marketing data,
which we analyze to develop business intelligence. We will continue to leverage this intelligence to optimize our marketing spending.



Growing our brand. We plan to invest in brand marketing initiatives that will further the association of Wix as the go-to platform for web
development and management. We believe this investment will further increase our long-term ability to acquire users.



Expanding to underserved geographic markets.We plan to make our product, support and communication channels available in more languages
to facilitate growth in underserved geographic markets. We also plan to expand our billing infrastructure in order to transact with multiple local currencies and payment methods across the globe.



Developing new solutions. We believe we have built unique technology that simplifies the process of building and managing a digital presence. We
intend to create additional value for our users, and increase our platforms monetization in the following ways:



Investing in product development to offer additional services. We plan to leverage our experience and knowledge in web development and workflow
management to build new solutions that businesses, organizations, professionals and individuals need to operate and succeed online. These additional paid services will improve our ability to grow and monetize our existing user base. We have a number
of product offerings already in development such as a variety of apps, data management and mobile solutions. For example, we recently launched an updated offering for mobile devices in September 2013. This new offering allows our users to design
their site so it fits numerous screen-size-factors (e.g., desktop, tablet and smartphone) yet will share design elements and all site data between the different variants. We believe this solution will enable our users to develop sites that provide
consumers easy access to business information and a way to interact with the sites owner, while adapting the design of the site for numerous screen sizes. We plan to further update our mobile offering to include the ability to customize and
modify sites from different devices.



Expanding our partner ecosystem. As our Wix platform serves tens of millions of businesses, organizations, professionals and individuals, we
attract interest from third parties seeking to efficiently market their services to these audiences. Although revenues derived from our App Market were negligible in 2012 and in the six months ended June 30, 2013, we are seeking to increase our
opportunities and thereby our revenues from the App Market by attracting more partners that will provide free and paid apps through our App Market as well as other features and services. While these partnerships are in the early stages of
development, they already contribute to the Wix ecosystem by enriching our solutions and creating additional monetization opportunities.

Our Offerings

We offer our web development, design and management
solutions and apps through an attractive online platform that enables our large user base of businesses, organizations, professionals and individuals to create a sophisticated and professional digital presence. Our web development technology is

work flow management applications and services. By registering with our website, our users receive access to the Wix Editor, an online editor that enables the user to design and manage an

The table below summarizes the different standard packages and levels of functionality that we offer as of the date
of this prospectus:

Free Products. Our users receive access to hundreds of free design templates for personal and
business use, free web hosting through the Wix domain, free apps from our App Market, and blog and social network page support. The websites developed using our free product contain Wix advertisements in the footer of the website, and tags, or
metadata, which contain our name. Our domain name is also contained in the link to the users website.

Our free product
and service offering includes the following features and capabilities:



Wix Editor. At the core of our platform is the Wix Editor, which currently supports five languages, and allows users to maximize their digital
presence by designing an unlimited number of websites, which are customizable using images, layouts, colors, fonts and other content provided by Wix, or content uploaded by the user, including visual and audio media. All websites designed using our



Wix SEO Tool. All of our products enable users to increase the visibility of their Wix website by using our Search Engine Optimization, or
Wix SEO tool. Through this tool, users may attach to their

sites a description and key words that relate to the site, so that web viewers or customers may find our users sites easily by searching for the descriptive or key words, using Internet
search engines. Our customer support team, through online video tutorials or one-on-one support, guides our users on the most efficient key words and site descriptions, in order to help users maximize the benefits of SEO and attain a larger digital
presence.

Premium Subscriptions. Our premium subscriptions are purchased primarily by businesses,
organizations and professionals in a variety of fields, such as art, finance, entertainment, music, beauty, sports or news. Premium subscriptions are not concentrated in any particular field. Our premium subscriptions offer all of the features of
our Wix Editor, but also include features tailored to business needs, such as eCommerce and appointment applications, and marketing tools such as Google Analytics and mailing lists. Our premium subscriptions also offer storage and bandwidth
for our users data and premium technical support services. We also offer ad vouchers with certain of our premium subscriptions, which allow users to expand their digital presence by advertising their pages on third-party sites, such as
Facebook and Google.

To date, most of our revenues have been from selling our Combo and Unlimited premium subscriptions. These
solutions are primarily purchased by businesses, organizations and professionals, which make up the substantial majority of our total user base.

Our premium subscriptions offer the following additional features and capabilities:



Connect Your Domain. All of our premium subscriptions allow users to connect their own domain name to their website, which means that the Wix
domain name will not be present in the users website address. The users domain name can also be purchased and managed directly through the Wix platform. Users who do not purchase premium subscriptions can also choose to purchase a domain
name as a stand-alone product, and continue using our free Wix Editor product to develop and maintain their website.



Google Analytics. All of our premium subscriptions give users access to Google Analytics, a third-party application that has the ability to
track the number of people that visit their website, the geographic location of their visitors, the length of time that visitors stay on their website, and the key words that were used to find the website. This feature allows our business users to
collect and use data for marketing and other commercial purposes.

Add Favicon. Our Combo, Unlimited, and eCommerce premium subscriptions allow users to change the Favorite Icon, or Favicon, that appears next to
the users page address and bookmark in most internet browsers. Users can change the Favicon that appears on the website by either uploading their own Favicon, or choosing one from our Favicons Gallery. This feature enhances the professional
design of users digital presence.



Wix eCommerce Solutions. Our eCommerce premium subscription allows our users to create a virtual store through which they may sell their
products online and process payments using an integrated shopping cart app, which is already included in the subscription. eCommerce users can tailor the style of the online store to their business, and with the shopping cart application, the users
may accept payment for products or services through PayPal. In the future, we plan to develop an upgrade to the shopping cart application, which will allow eCommerce users to accept credit card payments. Other eCommerce apps, such as shipping and
tax-calculation apps, may be separately purchased as add-ons through the Wix App Market.



VIP Services. We offer our VIP subscribers four additional features. Our VIP Support feature enables these subscribers to contact a
dedicated team of support specialists. If a support specialist is not available immediately, we will call the VIP subscriber back within a matter of minutes via our Priority Call Back service. In addition, VIP subscribers have the option
of receiving our Instant Response service during business hours via Wix Answers, our online automated ask-and-answer database.

Finally, we will review the completed sites of our VIP subscribers and provide feedback regarding how the sites structure and SEO can be improved via our Professional Site Review
service.

Applications and Value-Added Services



Wix App Market. The Wix App Market is an online platform that offers our users a range of software apps which can be seamlessly integrated as
add-ons into our users websites. The App Market includes over 140 free and purchasable marketing, social and media apps, as well as audio and visual content. Since the launch of the App Market in October 2012 through August 31, 2013, users had
installed 5,526,602 apps, 19,060 of which were purchased. Users gain access to apps in the App Market, and through our easy-to-use drag-and-drop technology they can install or remove as many apps as they would like within moments. The App Market
consists of apps that are developed by us or by third-party developers. Our research and development team creates our Wix Apps, and also tests and evaluates apps created by third-party developers. We have sales agreements with third-party developers
and we customarily share in 30% of revenues from the sale of every third-party app purchased through our App Market. We are responsible for the development, operation and maintenance of apps that we create, and the third-party developers are
responsible for the apps that they create. However, we may remove a third-party app at any time if it does not meet our standards or for other reasons.



Wix Databases. Our application development and data technology, Wix Databases is a platform that allows our users and developers to create their
own apps and work management tools, such contact forms and FAQ lists. This platform uses our drag-and-drop, style engine and smart layout technology, so that the user or developer may create professional-looking applications and tools with
customized styles, colors, and layouts. The apps and tools created through Wix Databases may be fully integrated into our users websites through publishing on the Wix Editor platform.



Wix Email. We offer users the ability to purchase Google email services with addresses linked to their Wix website domain. Wix Email features
advanced filtering and search capabilities, as well as automatic mail forwarding and responding. This product is integrated into our premium subscriptions, but is also available for purchase on a standalone basis.



Professional Services Marketplace. Through the Wix Arena Marketplace, found on our website, we provide a community for independent designers to
offer their audio or visual media content and personal web design services, using our platform. As of August 31, 2013, the Wix Arena Marketplace had 319 independent designers who offer web design and development content or services each month. These
independent designers are hired directly by our users and are responsible for negotiating the terms of service and price with such users. We provide a market for these services and are not a party to, and do not generate any revenue from these
agreements. We do not assume responsibility for the quality or cost of the services.

Customer Support

We offer our users the following support and services:



Wix Support and Call Center. Our customer solutions experts operate the Wix Support and Call Center. Our customer solutions team is responsible
for providing users with direct and indirect support, including monitoring and updating forums for user questions and knowledge databases, such as our online automated ask-and-answer database, Wix Answers. Because our support team is able to address
many of our users questions through these online and automated channels, direct customer support is often not needed to address user questions or technical issues. However, our support staff provides web-based technical support through chat,
email and remote support through the use of LogMeIn, a remote access program. The Wix Call Center also provides telephonic support during U.S. business hours and email support during extended hours. We do not currently offer telephonic support
outside of U.S. business hours. Our Support and Call Center employees offer telephonic and email support in the non-English languages in which we offer our platform  French, Spanish, Portuguese and Italian. For

example, our customer support staff and technical staff with Italian and Portuguese-language capabilities provide Italian and Portuguese-language support by updating forums in response to
customer questions and updating knowledge databases, such as Wix Answers, and translating the how-to videos in the Wix Support Center. We plan to hire additional employees with other fluencies as we add more languages and have already engaged a
small number of employees to provide telephone and email support in Japanese or Korean. As of June 30, 2013, we had 130 Support and Call Center employees, located in both the United States and Israel, 32 of whom offer direct customer service in
languages other than English and Spanish.



Wix Premium Support. All of our premium subscriptions contain access to Wix Premium Support. Those users with premium subscriptions receive
access to all the benefits of the Wix Support Center and Call Center, but they also receive priority access to our team of customer solutions experts, who prioritize premium subscription questions and requests over other user questions.

Selling and Marketing

Our selling and marketing expenses focus primarily on online advertising and we do not employ a direct sales force. Our main online acquisition channels include Google, Facebook and direct media
buying.

We market our solutions and apps to businesses, organizations, professionals and individuals, including entrepreneurs
and freelancers. We are able to attract a high volume of users and premium subscriptions by offering free solutions and services and upgrades and improvements to our premium subscriptions. We also offer 14-day money-back versions of our premium
subscriptions. As of August 31, 2013, we had more than 37 million users and 679,536 premium subscriptions across 190 countries. Our App Market averaged 19,762 installations per day during the month of August 2013.

We also provide a free co-working and event space in our two Wix Lounges, located in New York City and San Francisco. These lounges
provide designers who use our solutions, as well as freelancers, artists and entrepreneurs, with a workspace and an opportunity to network with others. We also host events at our lounges that allow our users the ability to showcase their work, free
of charge. We have found that our lounges enhance our brand and strengthen our network of users.

User Acquisition

We engage in online advertising with a focus on acquiring new users to our platform. We acquire the majority of
our users through free traffic to our website, primarily through search engine optimization or direct traffic, meaning visitor traffic that reached our website, Wix.com, via unpaid search results or by typing the URL of our website in their browser,
to our website, which includes customer referrals. We also acquire a small amount of free traffic through our participation on social networking sites and the banner advertisements we place on our non-paying users websites. In order to
increase our exposure and optimize organic, or free, search engine results, we constantly test our search engine optimization strategy to ensure that our website is relevant to those potential customers seeking web development and design products.
Further, we continually evaluate our marketing spending and its effectiveness and invest in those activities that are most likely to maximize our return by generating premium subscriptions. In 2013, we are continuing to focus our marketing spending
on channels that bring new users to visit, register and begin using our products and services.

We believe our user acquisition
strategy further benefits from the brand we have built as a leading web development and design platform for businesses, organizations, professionals and individuals. We believe that our branding efforts have accounted for a significant portion of
users who come directly to our website, through typing our URL directly into their browsers, or through searching for Wix or a term related to establishing a digital presence. We believe that these users are also attracted due to
referrals from other users, and via word-of-mouth regarding our products and services. Our acquisition strategy also benefits from our use of A/B testing on our website, a marketing approach that aims to identify changes to our website which will
increase or maximize user interest and acquisition. Our Design Studio team, consisting of 40 designers as of June 30, 2013, changes the

layout of our website from time to time, and engages in A/B testing in order to determine which layouts and graphics are the most successful in maximizing user acquisition.

Our marketing expenditures directed to advertising were $6.4 million in 2010, $15.9 million in 2011, $21.5 million in 2012 and $17.2
million in the six months ended June 30, 2013. Our marketing expenditures are directed toward the following channels:



Cost-Per-Click Advertising. We pay leading search engines to provide search results that provide our solutions and services with the maximum
exposure when users search for key terms related to establishing a digital presence. We do this both by elevating the placement of our website address in search results and by placing targeted display or banner advertisements on the search results.
We pay search engines on a cost-per-click, or CPC, basis each time a person clicks on such a paid search result or advertisement.



Online Presence and Branding. We have established an active online presence in social networking sites such as Facebook, Twitter, and Instagram,
and we also market our solutions by purchasing generic and targeted advertisements on these websites and others. We also consult public and media relation firms to help brand and advertise our solutions and services.



Other expenditures. A small portion of our marketing expenses are directed towards more traditional advertising, such as radio and television
commercials in the United States and Israel. We also maintain the Wix Affiliate Program, a program where our affiliates receive a commission for directing visitors to our website, by placing Wix ads on their personal websites. From time to time we
also hold webinars, promotional contests, user meet-ups and public relations events at our Tel Aviv, New York and San Francisco offices.

User Retention

Once we attract visitors to our website, our
preliminary goal is to register them as users. We distribute marketing and promotional emails and support tools to our registered users to help them build their site. These materials are created by our Wix Design Studio team, which complements our
marketing efforts by focusing on the consistency of our branding message online, in our offline merchandise and at our community events. Users who convert to a premium subscription gain access to additional features such as extra bandwidth and
storage, Wix ad removal, access to Google Analytics, domain connectivity and eCommerce solutions. We offer a 14-day premium subscription trial to introduce users to these additional products and solutions.
Users can choose either an annual or monthly premium subscription and as of August 31, 2013, 64% of our premium subscriptions were annual and 36% were monthly. We seek to increase the number of premium annual subscriptions by offering seasonal
promotions and discounts on annual subscriptions. We also send our subscribing users emails reminding them to renew their subscriptions before expiration, as well as coupons and other discounts on products and services. We seek to retain premium
subscriptions by offering upgrades for our premium products and free and premium apps in our App Market.

We further retain
premium subscriptions by developing relationships with subscribing users through the Wix Support and Call Center, a forum where we address our users technological needs and concerns. Through the Support and Call Center, we also help non-paying
users transition to premium subscriptions, by providing guidance on integration of premium subscription features into existing websites created with our Wix Editor. We seek to maintain goodwill with all of our users, and retain them as registered
users, even if they do not choose to subscribe to or renew their premium subscriptions.

Our Technology and Infrastructure

Our cloud-based platform provides our users with a suite of web design, development and workflow management products and apps, as well as
hosting for our users sites. All of these tools are accessible directly through our platform. In order to enhance our suite of products, we also conduct product and quality assurance testing on all new and existing technology integrated into
our platform.

We use a flexible hybrid cloud, comprised of both cloud-based storage and data centers, to host our products and apps, and the websites
that our users create. We lease our data centers from third parties. Our primary data centers are in two geographically separate locations in the United States with a back-up data center in Europe. We lease our primary data centers in the United
States from Hostway Services, Inc. pursuant to purchase orders issued under an agreement that automatically renews on an annual basis unless terminated by us by notice at least 60 days before the annual renewal date or by either party at any time
with 180 days advance notice. To date, we have not experienced any material outages or service interruptions. This highly-scalable multi-tenant technology enables us to serve all of our users simultaneously and consistently, and scales based on
overall traffic and capacity. As a result, our platform is not affected or slowed down by growth in the number of users in our cloud. Our cloud technology is also capable of full resource sharing, meaning that our users can access information via
their individual website database easily over the Internet without the need for manual download, with content delivery provided by proven international cloud delivery network vendors, such as Akamai and Level 3. To further ensure that all of our
data and our users data are stored safely, we also use Amazon and Google cloud services to backup our users data. In order to ensure that our cloud is protected from potential attacks or vulnerabilities, we engage in penetration testing
to expose and address any vulnerability in our technology.

HTML5-Based Design Capabilities

HTML5 is the latest and most advanced markup language available for structuring and presenting dynamic content on the Internet. Unlike
websites built using older HTML versions, websites using HTML5 can seamlessly incorporate video, audio, fonts, graphics and animations. Moreover, rich and interactive web design and app integration can be achieved without the use of Flash. Be
